The Evaluation And Rational Exploitation Of Geothermal Resoucres In The Geothermal Field In Suihua City, Heilongjiang Province

Energy is the foundation of human survival and development, and is one of theimportant material guarantee sustainable economic and social development and thenecessary impetus.As coal, oil, natural gas and other conventional depleted energy, thedevelopment of economy and large increase of energy consumption, energy reserves,production and use of the contradiction between the increasingly prominent, thedevelopment and utilization of renewable energy for the sustainable development ofnational economy and reducing greenhouse gas emissions, protect the environment willplay an important role.Geothermal resource is a kind of clean and renewable resources,has a wide prospect of development and application, such as used to generate electricity,heating, medical care, bathing, greenhouse, agricultural irrigation, etc.The geothermalresources development and utilization of the lindian county of heilongjiang province hasformed a sizeable inheritance pattern, created the remarkable economic benefits.DaQing city and Qiqi Haer city in recent years for the development and utilization ofgeothermal also produced scale.Sui Hua city is located in the east of songnen basinfringe area, the geothermal resources of Hei Longjiang province census blank space, theexistence of geothermal resources in the region to the east of songnen basin geothermalfield boundary extension of geothermal resources development and utilization of localregion and has very important significance.Sui Hua city is located in the east of Songnen plain, between Lesser KhinganMountains and Songnen plains.Songnen basin is a mesozoic rift basin, the earth’s crustis relatively thin, heat energy spillover, high heat, high temperature, high geothermalgradient, etc. Period of indosinian and yanshan period granite intrusion basal in thecarboniferous Permian shallow metamorphic rock, granite radioactive heat generated bythe heat production rate is high, and has s long persistence.But the degree of previouswork can’t satisfy the geothermal resources reasonable development requirements.Inorder to effectively protect the limited of geothermal resources, do scientific andreasonable mining, need to adequately and development and utilization of research forevaluation of the geothermal resources. In this paper, based on mineral resources compensation project in Hei Longjiangprovince--"pre-feasibility prospecting of geothermal resources in Suihua city,HeiLongjiang province ",take geothermal field in Suihua city as the research object,withregional geology and geothermal geology and geothermal fluid water chemicalcharacteristics data as the research basis, analysis of geothermal heat reservoir andcaprock and channels and heat source and recharge and runoff and drainage of thegeothermal fluid, and other characteristics. On this basis, the evaluation of geothermalreserves and geothermal fluid quality in the study area is carried out.
