The main thermal reservoirs of sedimentary basin type are the Neogene Guantao Formation and the Paleogene Dongying Formation.The thermal reservoirs of tectonic basin type are mainly the Ordovician Majiagou Group. The characteristics of reservoir, cap, pass and source of thermal resource types in different areas are elaborated. Based on the analysis of the wellforming conditions of the existing geothermal wells in the area, combined with the geothermal anomaly areas and hydrogeochemistry, it was discovered that the fault structures in the area, especially the deep faults such as Yuwangshan fault, Wangmushan fault, Zhangdian fault and Chaomizhuang graben, play an important role in controlling the occurrence and distribution of tectonic basin-type geothermal resources in Zibo City.展开更多
