Gaoqing area locates in Zibo city of Shandong province,where the geothermal resource belongs to malti-strata fissure-pore type. In the geothermal conceptual model, the main geothermal heat source has been the terrestrial heat flow of deep earth’ s crust, and the geothermal reservoir can be divided into 2 types, that is Neogene Guantao formation and Paleo-gene Dongying formation. Furthermore, Gaoqing Fracture may be the heat water transfer channel, the clay layers of Quaternary and Neogene Minghuazhen have been regarded as the cap rock. The geothermal resources assessment show that geothermal re-serves may be 1. 74 × 1019J and the exploitable reserves of geothermal fluid may be 6. 57 × 106m3/a,which can be used as the heat source of central heating . Absolutely, coal saving will be 25 879. 71 t/a and provide some great environmental benefit.
