摘要
通过广元地区龙门山前缘的遥感地质解译,野外地质考查以及结合前人地热水勘查成果,对其地热水的热源、水源、构造特征等综合分析认为,该区无附加热源,热源为深循环加热,水源以大气降水为主,具有深部循环的有利地质构造条件,为在正常的区域地温场背景条件下。出现在裂隙介质发育的深部碳酸盐岩地层之中的地下热水环流系统——中低温对流型地热系统,具有很好的勘探开发前景。
This paper analyses heat source,water source and the geological structures by studying field geological work,geological interpretation of remote sensing data and tectonic in front of Longmen Mountains in Guang Yuan area.The heat source is regarded as that the groundwater heated by itself deep circulation.There are no other heat sources.The water source is precipitation.There is thermal source due to the water heated by deep circle.At the normal regional background,geothermal circulation system-low medium temperature convective type geothermal system appears in the fractured media developed of deep carbonate rock,which has good potential for exploration and exploitation.
