Lindian geothermal field is 1960 ~ 1990 Daqing oil administration in lindian area oil and gas exploration found before 1997 has not been specialized research and geological survey. 1997 by daqing geothermal group of geothermal resources of lindian research and evaluation, after all the efforts of hydrogeologists, mastered the basic condition of lindian county geothermal field. 1998 in lindian county city ground In 1998, the first geothermal well was drilled in the city of Lindian County, marking the official start of geothermal exploration and development work in Lindian County. By 2004, the county has 21 geothermal wells, which have been applied to heating and cooling, bathing and recuperation, planting and breeding, industrial use and other fields, and from the primary stage of exploration and development to the industrialization of the operation, from the experimental demonstration stage to the scale of the operation of the transformation, and to promote the simultaneous development of the economy and society. At present, lindian county is in accordance with & ldquo; hot springs township & rdquo; naming standards, relying on & ldquo; hot springs township & rdquo; construction planning, organized to create a northern characteristics of & ldquo; China hot springs township & rdquo;. Lindian County - Overview 1.Natural Geography Overview Lindian County is located in the central and western part of Heilongjiang Province, the northern part of the Songnen Plain, belonging to Daqing City, Heilongjiang Province. From the provincial capital of Harbin City, 275 kilometers, 015 National Highway throughout the territory, is to Manzhouli, Heihe, Suifenhe and Russia's main traffic. County covers an area of 3,746 square kilometers, jurisdiction over 2 towns and 6 townships, 6 agricultural, forestry and animal husbandry reed farms, with a total population of 258,000 people. The terrain is flat, fertile soil, arable land of 1.9 million acres, 1.5 million acres of grassland, watershed area of 320,000 acres, reed ponds area of 480,000 acres, wetlands of 3.15 million acres, the climate of Lindian County is a continental monsoon climate, the four seasons of the temperature difference between the average annual temperature of 2.4 ℃, the average annual precipitation of 412 millimeters, the frost-free period of 129 days. 2. Overview of the geothermal resources of Lindian County, the Lindian region, from the perspective of the geologic structure of. Located in the northern part of Songliao Basin, north of Daqing Changyuan Lamaodian sub-tectonics, south of Uyur River Depression. The area from 1960 to 1990, Daqing Petroleum Administration after 30 years of oil and gas exploration, the area a total of 13 oil and gas exploration wells, by testing in addition to a few wells have a trace of natural gas show, the rest are mainly water, and water temperature is high, can be self-spraying. 1997 by the Daqing Geothermal Office organized scientific research departments of the characteristics of the geothermal resources in lindian county evaluation and research, and by the domestic geothermal expert assessment After the appraisal, it was unanimously agreed that Lindian geothermal field is the extra-large medium-low temperature geothermal field found in China so far. After detailed study, it proves that Lindian area gathers rich geothermal resources with static reserves of 181 billion cubic meters. Its characteristics: First, large reserves. Lindian geothermal field is located in the northern Songliao basin, since the Mesozoic era, the Songliao basin due to multiple tectonic movement fracture development, the formation of wide thick sandstone distribution area, thick sand layer, good porosity, so that Lindian County area underground are geothermal, initially determined that the Lindian County geothermal resources static reserves of 181 billion cubic meters; two is the low temperature. Lindian County geothermal resources buried relatively shallow, generally 900 to 2400 meters. From the currently developed geothermal well test, the wellhead temperature is constant between 40 to 90 ℃; Third, there is recharge. It is believed that, due to the outcrop of chalk system in the northern part of Songliao Basin, it is repeatedly infiltrated by precipitation, which makes Lindian geothermal field become a geothermal field with certain recharge; Fourthly, the water quality is good. According to the relevant state departments of Lindian County has been excavated geothermal wells water quality laboratory identification, the water contains silicon, strontium, nickel, lithium, zinc, selenium, iodine, manganese, iron, copper, boron and other more than 20 kinds of trace elements, and iodine-containing grade higher sodium carbonate type of mineral water, with a very high value of health care; Fifth, the pressure is great. From the geothermal wells have been excavated to confirm that the wellhead pressure of 0.4 ~ 0.5 MPa, pressure, can be year-round self-spraying, a single well day from the overflow of more than 1,500 cubic meters of water. Lindian County - Creating a Hot Spring Township Lindian County geothermal resources is the fifth largest resource found in Heilongjiang Province after coal, wood, grain and oil. Since 1997, always the geothermal as the development of economic pillar industries, around the creation of & ldquo; hot springs township & rdquo;, and actively introduce funds, projects, technology and talent, is committed to geothermal exploration, development and utilization of geothermal work, so that the development and utilization of geothermal resources made a breakthrough progress, led to the county's economic development. By the end of 2003, the county has 21 geothermal wells, including 8 new geothermal wells, oil and gas exploration wells to transform 13. Has been developed and utilized geothermal wells 7 eyes (Lin 4 wells, Lin deep 1 wells, Lin hot 1 wells, Lin hot 2 wells, Lin hot 3 wells, Lin hot 4 wells and Li 3 wells), applied to hot springs tourism, geothermal heating, bathing and recuperative treatment, mineral water production and planting and breeding and other fields, has achieved better economic and social benefits. At present, lindian county around the creation of & ldquo; hot springs township & rdquo;, promote the geothermal resources exploration, development and utilization, and has constructed a geothermal economic industry prototype, more and more show its huge development potential, lindian county tourism and economic development played a great role in promoting the & ldquo; hot springs township & rdquo; named conditions. As of the end of 2003, has completed a geothermal census, detailed investigation, exploration and other work; has entered the industrialization, scale development stage, the realization of geothermal heating 305,000 square meters, residential hot water supply 3610 households; the development of five hot spring tourism resorts. Among them: 4 hot spring bathing and recuperation centers and 1 indoor hot spring swimming pool. In 2003, the county's geothermal development project realized a total income of 240 million yuan. In 2003, the county's geothermal development projects realized a total income of RMB 240 million. 400,000 tourists were received throughout the year, and the tourism industry realized a total income of RMB 40 million. Compared with 1996 before the development of hot springs tourism, it has increased 8 times and 9.5 times respectively. The development of geothermal resources and hot springs tourism has greatly promoted the development of secondary and tertiary industries in the county, and a number of projects relying on the development of geothermal resources, such as food, beverages, medicine and beverages, have been put into operation, and the scale of business, beverage, service and urban construction has been improving and expanding. According to statistics, in 2003, the two or three industries realized a total income of 420 million yuan, accounting for 20.2% of the county's total output value, an increase of 33.3% over 1996. At present, geothermal development and hot spring tourism in the local economy has played a pivotal role, at the same time, also accelerated the promotion of lindian county to create & ldquo; hot spring township & rdquo; the pace. (A) the creation of & ldquo; hot springs township & rdquo;;, promoting the process of geothermal resources exploration Daqing City, Lindian area is the earliest large-scale exploration and development of geothermal fields in the Songliao Basin. Geothermal field discovery began in 1960 ~ 1990, after three decades of oil and gas exploration Daqing Oil Administration, found that the area has geothermal display. In order to speed up the exploration of geothermal resources in Lindian, change the exploration work no one to do & ldquo; upstream & rdquo; situation, in 1997, led by the government, funded the start of geothermal exploration work. After eight years of hard work, has completed the Lindian geothermal field survey work. 2002, around the creation of & ldquo; hot springs township & rdquo;, to further accelerate the process of geothermal resources survey. At present, the investigation of geothermal resources in lindian area has gone through a census, detailed investigation, exploration, boundary area survey and so on 4 stages, out of a scientific exploration and development development road. 1. census stage (1997 ~ 1998) In 1997, daqing city set up geothermal subject research group, began to lindian county area of daqing city, geothermal resources census work, collection and collation of the 13 eyes of the oil and gas exploration wells drilling, Geological logging, test wells, laboratory laboratory analysis data, collected water samples from 3 wells, carried out laboratory analysis of 15 water quality indicators, carried out temperature surveys, gravity surveys and other geophysical exploration work, after a detailed study of the isothermal map, circled the geothermal anomalies of the Lindian area. 1998, the first geothermal exploration wells were drilled in Lindian County, & mdash; & & mdash; Linzhe mdash; forest heat 1 well, well depth 2718 meters. In 1300 & mdash; 1680 m well section, has revealed the water temperature of 54 ℃, since the overflow of 1200 cubic meters / day of geothermal water, in the 1700 ~ 2718 m well section was also found to be endowed with the water temperature of 60 ~ 70 ℃, the water volume of 700 ~ 800 cubic meters / day of geothermal water. Completed the geological census stage of the Lindian geothermal field in Daqing City, confirming that the territory of Lindian County is rich in geothermal resources.2. Detailed investigation stage (1999-2000) After the geothermal census, further geothermal drilling at the same time, carry out regional geological surveys, and strengthened the geophysical exploration. Basically identified the geological structure of the Lindian geothermal field, more accurately delineated the location of the fracture, circled the geothermal fluid-rich areas; identified the spatial variation of the temperature field within the geothermal field, calculated the thermal storage temperature and geothermal reserves; and made a clear explanation of the conditions for the replenishment and transportation of geothermal fluids. At this stage, two geothermal exploration wells (Linhe 2 and Linhe 3) were constructed, with a total footage of 4,056 m. Based on the analysis and study of logging data and temperature data, combined with the analysis data of oil and gas exploration wells, it was concluded that the Lindian geothermal field had entered the water storage sand layer, and the rate of geothermal warming was 3.5℃/100 m. It was established that the reserves and recoverable amount of the geothermal field were determined, and the geothermal field of Lindian with a total area of 183 sq. km was completed. Geothermal detailed investigation, in 2001, Heilongjiang Provincial Department of Land and Resources approved the geothermal detailed investigation report.3. Exploration stage (2001-2002) Exploration stage is the stage of geothermal field establishment. While accelerating geothermal drilling and obtaining detailed geological data, relying on the results of the detailed investigation, we strengthened geological research, identified the causes of thermal fluid, recharge pathways, and calculated the service life of the geothermal field. The exploration of Lindian geothermal field has gone through two periods, one is shallow exploration (well depth below 2000 meters). During this period, a total of 6 geothermal wells were drilled, with a depth of 1800-2050 meters, completing the shallow exploration of Lindian geothermal field; the second one is the deep exploration (2000-3000 meters). In January 2002, in order to explore the geothermal resources in the deep part of the Lindian area, a deep geothermal exploration well was completed in the southern part of the county, with a depth of 3000 meters. So far, the exploration work of Lindian geothermal field was finished. Conclusion: Lindian geothermal field area of 3,746 square kilometers, geothermal field has a more adequate water supply, 2000 meters to shallow in low temperature (40 ~ 54 ℃) geothermal water is sufficient, water quality is better, more suitable for the development and utilization; deep geothermal resources, the water temperature is high (bottom of the well temperature of 101 ℃/3,000 meters), the water is small, the development and utilization of the cost of higher, is not easy to develop.4. Boundary area investigation stage ( 2002— 2003) Boundary area investigation is to determine the basis of the geothermal field area, in the detailed investigation stage, has completed the Li 3 wells in the south of Lindian County and fish 13 wells, the northern forest deep 1 wells and 4 wells, the eastern fish 1 wells, such as the study of 5 oil and gas exploration wells, to determine the location of the geothermal field of the south of the Lindian, the north, the east of the three-way boundary area. In order to determine the western boundary of the geothermal field, a boundary area investigation well —— Linhe 7 well was drilled in 2002 at the western boundary edge of Lindian County (buffer zone of Zalong Nature Reserve) with a depth of 1,850 meters, a water temperature of 52 ℃, and a daily self-spillage of 60 cubic meters, which determined the western boundary of the field, and completed the investigation of the boundary area of the geothermal field in Lindian. (B) the creation of & ldquo; hot springs township & rdquo;, promote the scale of development and utilization of geothermal resources 1. hot springs tourism continues to develop and grow Around the creation of & ldquo; hot springs township & rdquo;, combined with the natural conditions of lindian county is unique, geographically advantageous, rich in geothermal resources. In order to achieve a reasonable combination of resource conditions and geographic location, better play the advantages of resources, in line with the principle of careful planning, strengthen management, to achieve the development and utilization of resources & ldquo; three & rdquo; change, that is: from the government development to the socialization of the development of changes in the dispersal of small-scale development to the transformation of large-scale development, from the development of the rough development to the transformation of the characteristics of the type of development. At present, lindian county hot springs tourism has been built in 1986 by the heilongjiang province army retired cadres sanatorium, developed into a hot springs sanatorium, hot springs health care, hot springs vacation, hot springs sightseeing, hot springs swimming and other tourist attractions.

Mineral water development reputation of the country According to the Lindian County geothermal water on the human body has a certain health care, can be used for the production of health care-type characteristics of mineral water. 2000 years investment of 40 million yuan in LinShen1 wells. In 2000, we invested 40 million yuan to build a 100,000-ton Shengfuer mineral water project in LinShen 1 well. After put into production, the product has been recognized and praised by China Mining Association and China Food Industry Association, and recommended as green drink. Now in Harbin, Dalian, Qiqihar and other cities to establish more than 30 sales outlets. 2003 production value of 210 million yuan. At present, the project expansion project is being carried out, to introduce two Italian production lines, the annual output of 300,000 to 500,000 tons. At the same time, it is studying the development of fluorine-rich mineral water, ready to enter the low-fluorine areas at home and abroad. 2002, in accordance with the "National Standard for Drinking Natural Mineral Water", after researching with the relevant experts, it was decided to make use of the existing geothermal wells to look for the drinking natural mineral water layer, and to develop the natural drinking mineral water. 2003, in July, the mineral water exploration project was carried out in the LINZHE 2 wells, and the implementation of the project was completed in September, and it found a water layer that meets the requirements for drinking water in the layer section of 600～800 meters. 800 meters section found in line with the natural mineral water for drinking water layer, for the next step in the large-scale development has laid a solid foundation.8. Alternative industries in the ascendant Heilongjiang Province is a large province of oil and coal production, Lindian County belongs to the Daqing City, currently in the world's increasingly tense energy today, petroleum and coal as a sunset industry, engaged in petroleum and coal mining and processing of enterprises are actively looking for a new alternative industry. Geothermal as a new type of energy, after a few years of development and utilization of Lindian County, not only for the economic development of Lindian County to find a new way, but also for the oil, coal production and processing enterprises to find a new alternative industry, but also for the Songliao Basin and even the three northern regions (Northeast, North China, Northwest China) of the exploration, development and utilization of geothermal resources to play a demonstration role. (C) the creation of & ldquo; hot springs township & rdquo; improve the management of geothermal resources Geothermal resources is a clean mineral resources, extremely valuable and limited. Over the past few years, in order to rationally develop, utilize and protect the resources, adhere to the resource-oriented, environmental priority, development and protection of the principle of equal importance to legislation, planning, science and technology and capital investment as a breakthrough, focus on the protection of resources, strengthen the management, to ensure that the resources to achieve sustainable use.1. Combined with the actuality, the development of the management approach Legislation is the basis and foundation for the protection and management of geothermal resources. Combined with the Lindian County geothermal resources development hot springs tourism development of the actual situation, in order to ensure that the geothermal resources in & ldquo; development in the protection, in the protection of the development & rdquo;, the realization of the sustainable use of geothermal resources, to prevent the phenomenon of indiscriminate exploitation of wasted resources, so that the development and utilization of geothermal resources in Lindian County, there is a law to rely on. According to "Mineral Resources Law" and "Mineral Resources Law Implementing Rules" and other laws and regulations of the relevant provisions, combined with advanced management experience in foreign countries, in 2000 developed and introduced the "Lindian County Geothermal Resources Provisional Management Measures", clearly defined the exploration, development, utilization of geothermal resources, responsibilities, obligations, protection and penalties and other relevant provisions, so that Lindian County geothermal resources management on the legalization of the track, which promotes the development and utilization of geothermal resources. Lindian County geothermal resources development and utilization in an orderly and healthy manner. 2.Relying on planning, scientific use of geothermal resources Planning is a measure of scientific management, but also the implementation of rational development and utilization of resources based on. Lindian geothermal field area is large, in order to ensure the scientific exploration and development of Lindian geothermal field. 2001 in Heilongjiang province land and resources department support, by the Heilongjiang province hydrogeology engineering survey institute completed the "lindian geothermal field geothermal resources development and utilization and geological environmental protection master plan", "planning" is in line with the geothermal development planning and urban construction master plan combination of the principle, clear lindian county geothermal field Firstly, in line with the principle of combining geothermal development planning and urban construction master plan, it specifies the distance between wells, well position, well depth, water-taking layer section, single-well mining volume, protection measures of geothermal field and the way of geothermal resources' graded utilization; secondly, it adheres to the principles of unified planning, rational development, focusing on effectiveness, development and protection, and gradually establishes a more scientific and advanced system of geothermal resources' development and utilization. Third, combined with the expansion and development of hot springs tour, combined with geothermal resources, grass reed scenery and natural landscape, do & ldquo; China's hot springs township & rdquo; project construction planning. 2002 by the shandong dazheng group compiled lindian county geothermal resources development and utilization of the & ldquo; a line of three gardens & rdquo; planning, "the planning" is divided into three functional parks, namely, hot springs tourism and recreation park, Hot springs ecological agriculture park and geothermal geopark, constructed lindian county hot springs tourism grand prospect, open up the hot springs tourism new ideas, set up a big industry, big tourism, big market concept, for the creation of & ldquo; China hot springs hometown & rdquo;;, has laid a solid foundation. 3.Strengthen the protection, the implementation of geothermal recharge Geothermal recharge is to ensure that the realization of geothermal resources to achieve sustainable use of the effective measures Geothermal recharge is one of the effective measures to ensure the sustainable utilization of geothermal resources, but also to protect the geothermal resources, to prevent ground subsidence and geothermal tail water pollution of the environment is an important means. Lindian geothermal field is a ground pressure type geothermal field, since 1998, due to the geothermal mining is increasing, the release of stratum pressure, geothermal wells water level slightly downward trend, so as early as possible to carry out the geothermal recharge is very scientific and necessary. 2002 in the county drilled a geothermal recharge wells, wells 2,000 meters deep. Due to the current stratum pressure (0.4 ~ 0.45 MPa) is large, did not implement the recharge, to be stratum pressure reduction, choose a reasonable stratum, the development of recharge measures timely recharge, in order to ensure that the geothermal resources are effectively protected and realize the sustainable development and utilization of the 4. Relying on science and technology to achieve the management of information technology Lindian County is the development of the utilization of geothermal resources in Heilongjiang Province is a more successful counties, but also relying on geothermal resources It is also the first county to develop and expand tourism based on geothermal resources. At present, the county has 21 geothermal wells, the development and utilization of 7 eyes. With the increasing number of geothermal development projects, the amount of geothermal mining gradually increased, but also for the management of geothermal development has put forward a new topic, how to use scientific and technological means, the implementation of scientific management of geothermal resources.
