In order to understand the status of geothermal resources in eastern Yangxin County,the geothermal reservoir of Neogene Guantao Formation is taken as the research object.Through data collection,geothermal geological survey,geo-thermal drilling,productivity test,water quality detection and analysis,the geothermal geological conditions and thermal reservoir characteristics in this area are identified,the conceptual model of thermal reservoir is established,and the geo-thermal resources of Guantao Formation thermal reservoir are calculated.The results show that the top surface of the ther-mal reservoir of Guantao Formation in this area is 940 to 1 100 m deep and the thickness of the thermal reservoir is 200 to 345 m,which belongs to the layered pore-fracture type thermal reservoir.The amount of geothermal resources stored in the geothermal reservoir is 9.677 3 ×10 18 J,and the amount of geothermal water recoverable resources is 2.171 3 × 10 7 m3/a.33 geothermal wells can be arranged in this area,and the reasonable well spacing is 3 950 m.The research results can provide an important basis for the development and utilization of geothermal resources in Yangxin County and the planning and management of local geothermal resources.
