Study On Geothermal Geological Conditions And Prospect Evaluation Of Geothermal Resources In Yabuli Area,Heilongjiang Province

With the economic development and energy conflicts become increasingly prominent,the demand for new energy is growing.Traditional energy sources,such as coal,oil,natural gas,etc.,are often accompanied by environmental pollution during use.Compared with traditional energy sources,environmentally friendly renewable energy has many advantages,and the development and utilization of green energy has become the new trend of today's social development.Geothermal resources due to its extensive distribution and renewable gradually become an important part of the future of new energy,is being payed more and more attention.Shangzhi City,Heilongjiang Province Yabuli area to tourism projects,because it has successfully held a major domestic and international major ski events and famous,which Yabuli ski resort and the National Forest Park renowned overseas,has been established as the annual meeting of the China Entrepreneurs Forum permanent Site,was praised as "China's Davos",is China's largest international tourism ski resort.However,due to the Yabuli area is located in the mid-latitude cold zone,the annual heating period is longer,the average annual snow cover for up to 170 days,life heating and heating needs to consume a lot of coal,which has become the local winter air pollution is one of the most important pollution sources,and thus the development of local new energy,to solve the shortage of local resources urgently.Heilongjiang Province,the development and utilization of geothermal resources later,the early focus on Daqing City,Qiqihar City and other places,and more for heating and heating,bathing and aquaculture and other fields,and has achieved good economic benefits,the environment benefits and social benefits.One of the most significant is Lindian County,the city within the scope of the new building to achieve the basic realization of the hot water into the household,ordinary people to open the home of the faucet,you can use the hot water to facilitate the masses of daily life.Geothermal energy is not only used to heat the residents,in the Evergreen Forest Farm also built a geothermal heating of vegetable greenhouses,made a good income,and promote the local economic development.In recent years,the development of geothermal resources has expanded to the whole province.However,due to the limitation of geological conditions,the band-shaped heat storage in bedrock area has many reasons such as less distribution,deep storage,complicated geological environment,difficulty in drilling and construction,is still in its infancy.In this paper,by analyzing the geothermal geologic conditions of Yabuli area in Heilongjiang Province,using the results of geophysical interpretation in the census stage,delineation of geothermal enrichment zones.According to the parameters obtained by over-drilling,geophysical logging and buck test,the geothermal resources of geothermal area are comprehensively surveyed and evaluated.The thermal storage of the work area is in the granite fault zone,and the heat storage is in the zonal distribution.Mainly to study the distribution of control or influence the geothermal resources of the fracture structure form,the scale,occurrence and their combination relations,combining with the geophysical exploration for delineating the boundary of the geothermal fluid enrichment region,and by setting the geothermal wells in the fault zone on the initial identification of geothermal geological conditions.According to the geothermal geologic conditions of the geothermal area,the physical and chemical characteristics of the geothermal area are evaluated,the parameters of the geothermal resources are calculated and evaluated,and the geothermal fluid can be estimated.The development feasibility of zonal thermal storage geothermal resources in the rock area is to provide decision-making basis for further exploration and development of geothermal resources in Yabuli town ski resort in Shangzhi city.Considering the above results,combined with the local geothermal geologic environment,the geothermal resources of the Yabuli area are evaluated.In addition,the local geothermal resources belong to the fissure type thermal storage.The development of the rupture type geothermal resources is widespread and widely distributed.The geothermal resources of this type are studied,which provide the theory for the same type of geothermal resources and the development and evaluation of resources in northeast and similar areas reference.
