Geothermal resources in the eastern Liaocheng geothermal field of Shandong Province

Geothermal resources are very rich in the geothermal field of eastern Liaocheng,Shandong Province. Geological-structural conditions and geothermal reservoirs there are relatively favorable for the exploitation of these resources.Based on drilling data and recent research results,the author considers that the Liaocheng geothermal field belongs to the karst fissure layered conductive type,with the regional geological structures being mainly composed of Liaokao fault and Chiping fault,and the hot reservoir chiefly comprised of limestone strata of Ordovician Majiagou Formation.The geothermal gradient of the area is controlled mainly by structure,the structural heat conduction is a key factor for the formation of this area,the mineralization intensity of the geothermal water is low,and the geothermal water contains some useful mineral components.Some suggestions concerning the reasonable development of geothermal resources and some policies for solving problems in current exploitation work are also put forward in this paper.
