Study On Geothermal Resource Potential Of Tailai

Currently, oil, coal, natural gas and other fossil fuels have been accounted for more than85 percent of the world total energy for human consumption. Mankind has created unprecedented prosperity material; it is also facing a serious problem of resource depletion and environmental pollution problems. Geothermal energy resources as a new leader in the family, should contribute to the energy conservation, prevention of air pollution. Tailai County is located in Qiqihar City, located in Heilongjiang, Jilin, Inner Mongolia junction, belonging to the Daqing oil field exploration area. Tailai County is located in the northeast old industrial region, its energy is mainly dependent on coal, oil, natural gas and other fossil fuels. Winter heating for a long time, requires a lot of energy and often appears haze. Tailai County has beautiful scenery and abundant natural resources, known as the "land of plenty." It utilization of geothermal resources can save energy, air pollution prevention, can promote the further development of tourism and bring good economic benefits, environmental and social benefits.The study mainly based on oil exploration well logging data, logging data, exploration results Basin, analyzes the Tailai County geothermal energy sources and main controlling factors.research on geothermal field characteristics in different depths and the deposition conditions of different formation units, analysis the characteristics of geothermal reservoir,analysis the hydrogeology characteristics of the groundwater, evaluate the geothermal resources. Based on the calculation results of geothermal resources, in order to be more intuitive determine the distribution of geothermal resources, opt the target area, calculate the geothermal resources abundance, that geothermal resources in the plane of the distribution,for every square kilometer of area contained heat.The study results show that Tailai County has a high geothermal gradient and terrestrial heat flow background, geothermal gradient value distribution in the range of 3.1~5.0?/100 m.Granite wide distribution, deep fault between the heat source and the upper deep geothermal reservoirs is the good channel. The main geothermal reservoir is Yaojia, Qingshankou,Quantou. Water is alkaline water of NaHCO3. The total reserves of geothermal resources22.04 × 1018 J, equivalent to about 759 million tons of standard coal. Tailai County geothermal resource abundance 0~28.3×1012KJ/Km2.Geothermal resource development is favorable in Ningjiang,Hamutai and north-eastern regions.
