聊城市城区地热资源及开发利用

Exploitation and Utilization of Geothermal Resource in Liaocheng City

聊城市城区位于临清潜陷区和鲁中隆起区的接合部位,地热成矿地质条件有利。地热类型属层状裂隙-孔隙型和裂隙-岩溶型,可被利用的热储层主要有3个,分别为新近纪馆陶组、古近纪东营组裂隙-孔隙型热储和寒武-奥陶纪裂隙-岩溶型热储。3个热储层水温、水质各具特点,均具有较好的开发利用价值。

Liaocheng city locates in the combining section of Linqing depression and Luzhong uplift whtch has favorable condition for forming geothermal resource. Geotherm in this area majorly belongs to malti- strata fissure-pore type and fissure- karst type. There are three kinds of geothermal reservoirs available, such as Neogene Guantao formation,Paleogene Dongying formation fissure-pore type geotberm and Cambrian-Ordovician fissure-karst type. All these three kinds of geothermal reservoirs have high exploration and utilization value, and each has its own characteristics of water quality and water temperature. Geological condition of geotherm, characteristics of ground temperature field and water quality in this area are analyzed in this paper, and few problems occurred in exploitation and utilization are studied as well.
