摘要
山东省聊城西部地热田位于临清拗陷内的莘县凹陷的南部,面积约1280 km2。通过已有钻探资料及近年的勘查项目研究成果,对聊城市西部地热田的地热资源的地质背景、水文地质特征、地球物理化学特征等进行了综合研究分析,认为聊城西部地热田属于层控型低温地热田,热储层主要为新近纪明化镇组下部、馆陶组、古近纪东营组地层,该区的地温梯度主要受构造控制,断裂导热是形成本区的一个重要因素,地下热水矿化度较小,成因主要为大气降水。
Geothermal heat in west part of Liaocheng locates in south of Shenxian sink in Linqing depression with the square of 1 280 km^2. This article synthetically analysed 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 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.
