【摘要】 山东省聊城东部地热田内蕴藏着丰富的地热资源,地质构造条件、热储地质条件都比较有利,是开发地热资源的有利地段。通过对已有钻探资料的分析,结合近年来的勘查项目研究成果,笔者认为聊城东部地热田属于岩溶裂隙层状传导型地热田,区域地质构造主要为聊考断裂和茌平断裂,热储层主要为奥陶纪马家沟组灰岩地层,该区的地温梯度主要受构造控制,断裂导热是形成本区地热田的一个重要因素,地下热水矿化度较小,含有多种对人体有益的矿物、元素,并且根据开发现状提出了合理的开发利用与保护政策。更多还原

【Abstract】 Geothermal resources are very rich in the geothermal field of eastern Liaocheng,Shandong Province. Geological-structural conditions and geothermal reservoirs there are relatively favorable for the exploitation of these resources.Based on drilling data and recent research results,the author considers that the Liaocheng geothermal field belongs to the karst fissure layered conductive type,with the regional geological structures being mainly composed of Liaokao fault and Chiping fault,and the hot reservoir chiefly comprised of limestone strata of Ordovician Majiagou Formation.The geothermal gradient of the area is controlled mainly by structure,the structural heat conduction is a key factor for the formation of this area,the mineralization intensity of the geothermal water is low,and the geothermal water contains some useful mineral components.Some suggestions concerning the reasonable development of geothermal resources and some policies for solving problems in current exploitation work are also put forward in this paper.更多还原
