Evaluation Of Geothermal Resource Potential In Liaoning Province

This study collects geothermal exploration data from Liaoning Province,comprehensively uses thermal storage method,fuzzy comprehensive evaluation method,GIS,etc.to evaluate the development potential of geothermal resources in Liaoning Province at present,and to explore the potential for future exploration and utilization of geothermal resources in Liaoning Province.Conduct predictions and evaluations.Using the heat storage method,the calculation proves that the amount of geothermal resources in Liaoning Province is huge.Based on these geothermal resource data,the fuzzy comprehensive evaluation method is used to determine the geothermal development and utilization evaluation index system,select 9 relevant indicators that affect the development and utilization of geothermal resources in Liaoning Province,and use the expert scoring method to synthesize the current potential of the development and utilization of geothermal hotspots.Evaluation.Based on the evaluation of the potential of development and utilization of geothermal resources in Liaoning Province,this paper uses GIS software to predict the possible location of geothermal resources in the future potential area.Four evidence factors of fault,basin,intrusive rock and water system were selected,and the distance map of the hotspot to evidence factor generated by the Euclidean distance tool in GIS was used.The weighting method is introduced to determine the weight value of each factor.The grid calculator tool is used to obtain the prediction map of geothermal resource potential in Liaoning Province,and the location range of the future potential area of geothermal resources is determined.The location range covers: Fuxin,Jinzhou,Yixian Interchange;Chaoyang City in Chaoyang Basin;Dalian City and its counties and cities;Huludao,Jinzhou,Chaoyang City in Liaoxi,and Damin Basin in the Lower Liaohe Plain Near Panjin.Based on the current evaluation of geothermal resources in Liaoning Province and the prediction and evaluation of potential areas in the future,this study made a comprehensive evaluation of the overall potential of geothermal resources in Liaoning Province.In view of the different types of geothermal resource potential areas,it is proposed to better serve the Liaoning society and serve the development of Liaoning economy.Liaozhong,Liaodong and Liaonan are the potential areas for development and utilization at this stage.On the basis of development and utilization,it is necessary to enrich the development model to promote the diversification of development models and strengthen resource conservation.The future geothermal resources in western Liaoning and northern Liaoning have great potential.In the forecasting area,effective technical means should be used to increase the intensity of exploration,discover more new geothermal resources,and draw on the experience of other regions,and rationally plan the development and utilization mode of future geothermal resources.
