Division of geothermal resources in northern Jinan

Abstract：There are abundant low and middle temperature geothermal resources in northern Jinan. According to geothermal gradients, geological-tectonic conditions and geothermal reservoir types, the geothermal resources can be divided into preferred exploitation area, relatively preferred exploitation area, somewhat preferred exploitation area, and common exploitation area. Considered from economically recoverable geothermals, the target beds for preferred development are Guantao Formation and Paleozoic Cambrian-Ordovician carbonite. Taking Qi-Guang fault as the boundary and following the principle of giving priority to the easy task and combining the shallow one with the deep one, the authors have reached the conclusion that, to the north of Qi-Guang fault, the main task should be the exploration and exploitation of Neogene Guantao Formation and, to the south of Qi-Guang fault, attention can be paid to the exploration and exploitation of Cambrian-Ordovician limestone thermal reservoirs.
