绥宁县寨市乡地下热水的潜力分析

Potential Analysis of Underground Hot Water in Zhaishi Township,Suining County

本文以绥宁县寨市乡为例,勘察地下水形成的水文地质条件,分析地下热水的潜力。其间通过勘察地层岩性、断裂构造分布、产状、导水性和各地层裂隙,推断区内热储、盖层、导水与控热构造,对浅表地温场进行测量,查明区内的地温场、地温梯度空间分布特征,综合分析热源、热储以及盖层等地下热水形成的基本条件,寻找可能的异常范围,选定地热勘查靶区,为下一阶段地热钻探提供依据。

Taking Zhaishi Township,Suining County as an example,this paper investigates the hydrogeological conditions of groundwater formation and analyzes the potential of underground hot water.During this period,by investigating stratum lithology,fault structure distribution,occurrence,water conductivity and fissures in various strata,the thermal storage,caprock,water-conducting and heat-controlling structures in the area are inferred,the superficial geothermal field is measured,and the spatial distribution characteristics of the geothermal field and geothermal gradient in the region are identified,the basic conditions for the formation of underground hot water such as heat source,heat storage and caprock are comprehensively analyzed,the possible abnormal range is found,and the geothermal exploration target area is selected,so as to provide the basis for the next stage of geothermal drilling.
