Abstract: On the basis of the analysis of Tengzhou geothermal field, geothermal geology, hydrogeology, and coal field geology, this paper comprehensively studied the deep geothermal characteristics of geothermal fields, described the thickness of the Ordovician layer, established a thermal reserve concept model, and believed that the research area has good thermal, source, access and cover conditions.Characterizing the shallow ground temperature field as an entry point, we calculated the depth and temperature of the base plate of the thermal band, and determined two shallow ground temperature anomalies.We calculated the gradient of the ground temperature and found that the gradient varied greatly in the study area, and there were obvious anomalies in the ground temperature.The anomalous zone of the ground temperature gradient is mainly controlled by regional geological structure and overlaps with the anomalous zone in the shallow northeast.The temperature of buried thermal reserve at 1 500 m was predicted, the geological conditions and characteristics of mid-deep geothermal were analyzed, a mid-deep geological anomaly zone was identified as the most favorable site for thermal source, and the plane morphology of mid-deep geothermal anomaly zone was figured out.The geothermal resources of karst thermal reserve in this abnormal area are estimated to be 20×10¹⁸ J,and the recoverable geothermal resources are 3×10¹⁸ J,which is equivalent to the thermal production of 1.02×10⁸ tons of standard coal.The results of our research can provide scientific basis and decision-making references for the study of geothermal geological conditions in the research area, follow-up exploration, and standardized development and utilization of geothermal energy.
