以岩石电性特征差异为基础的电测井,在金属矿产、地下水资源勘探中,发挥着重要的作用。在视电阻率测井装置中,地井系统是较为常用装置形式。通过安徽省胡家碾地区地质背景和钻孔地层以及对井中电法测量资料的分析对比,探讨了井中地电异常产生的原因及与寻找地下水的关系,认为井中负视电阻率异常与井中正自然电位异常相对应时,通常是寻找地下水的有利地段。

Electrical logging which is based on differences of rock electrical characteristics plays an important role in metal minerals and groundwater resource exploration.The well system is more commonly used in the apparent resistivity logging device.In this paper,through analysis and contrast of geological background,drilling strata and electric measurement data in wells,origin which caused electrical anomalies and searching for groundwater have been studied.It is regarded that when the negative apparent resistivity anomalies in the wells is corresponding with spontaneous potential anomalies,it is usually the favorable section for searching groundwater（or even expected to find favorable areas of high temperature hot water）.
