聊城市地热资源的形成及开发利用

研究区在地质构造上属于华北地台的一部分，通过聊城市东侧的聊考大断裂将本区切割成东西两大部分．断裂两侧储存着丰富的地热资源，地下热水主要赋存于新近系馆陶组和奥陶系地层中。奥陶系热储层埋藏较浅，单井涌水量45-80m^3／h，水温53℃-68℃水质相对较好．是未来理想的开采层段。区内热源主要来自于地壳深部热流的地温传导和更深部的热流通过聊考深大断裂带的上涌。聊考深大断裂具有一定的导热导水作用．地下热水及热量在此处易集中。地热水中氟含量达到医疗价值浓度，偏硼酸、偏硅酸达到矿水浓度或医疗价值浓度。地热水在低温地热供暧、医疗保键、水产养殖和旅游方面有一定开发价值。

The Formation of Geothermal Resource and Exploitation,Utilization in Liaocheng City

The study area is a part of North China platform tectonically. The Liaocheng-Lankao major fault pass through east side of the Liaocheng City and divided the area into east and west two parts, abundant geothermal resources are existing in both sides of the fault and mainly hosted in Guantao Formation, Neogene System and Ordovician System strata. Ordovician System geothermal reservoir is rather shallow, individual well yield is 45-80m^3/h, water temperature 53℃-68℃, water quality rather good, is the ideal mining sector in the future. The thermal source of the area is mainly geothermal conduction of thermal current from depths of the crust and deeper thermal current upwelling through Liaocheng-Lankao major fault zone. The major fault has certain thermal and water conducting capability, underground thermal water and heat are easy to concentrate here. Fluorine concentration in geothermal water is accord with medical treatment requirement, metaboric acid and metasilicic acid concentrations are accord with mineral water or medical treatment requirements. The geothermal water has certain exploitation value for low temperature geothermal heating, medical treatment and health care, as well as aquaculture and tourism.
