摘要
剑阁县清江湖地热水属于封闭还原条件的三叠系雷口坡组灰质白云岩和嘉陵江组灰质白云岩、灰岩深层岩溶水,上下为三叠系须家河组和铜街子组厚层泥岩、页岩相对隔水层,热储层具有良好的盖层条件。西北侧补给区接受大气降水补给后,经过海相沉积的含岩盐地层,在长距离、深循环过程中发生强烈的水–岩相互作用,析出大量岩石中的有用组分。同时,在正常地温梯度增温作用下,地下水向下深循环过程中逐渐加热,形成了含偏硼酸、偏硅酸的锶、氟、硫化氢理疗热矿水。本研究对于大尺度、大范围开发同类型地热资源具有重要的理论价值和现实指导意义。
Qingjianghu geothermal water of Jiange County is belongs to the closed reduction conditions of the deep karstwater in the Permian Leikou slope group gray matter dolomite and Jialingjiang group gray matter dolomite&limestone.Theupper and lower layers are the thick mudstone of the Triassic Xujiahe Formation and the Tongjiezi Formation,and the shalehas a good cap rock condition with respect to the aquifer and the thermal reservoir.In the northwest side of the recharge areato accept the precipitation of atmospheric precipitation,after the marine sedimentary rock salt strata,in the long distance,deepcycle of the process of strong water–rock interaction,precipitation of a large number of useful components in the rock.At thesame time,under the effect of normal temperature gradient,the groundwater is gradually heated downwards to form hotmineral water containing meta-boric acid,metasilicic acid,strontium,fluorine and hydrogen sulfide.This study has importanttheoretical and practical significance for development of geothermal resources of the same type.
