摘要

Geothermal heat in west part of Liaocheng locates in south of Shenxian sink in Linqing Depression with the square of 1 280 km². This paper synthetically analyzed geological background, hydrogeology characteristics, the earth physical and chemical characteristics. Liaocheng geothermal field is a kind of strata bounding and low temperature geothermal field. The hot reservoir is mainly composed of the lower part of Minghuazhen Group and Guantao Group in Neogene and Dongying Group in Paleogene. Geothermal gradient in the area is controlled mainly by structures, and the structure heat conduct is a key factor for the geothermal field formation. The geothermal water mineralization degree is less and is mainly the atmosphere precipitation source.
