摘　　要：利用井中激电可判断井底、井旁是否有盲矿,在确定矿层厚度、埋深及延伸方向等方面都取得了一定的地质效果。在陕南旬阳某工区ZK5003钻孔进行激电测井,结合工区的岩(矿)石电性参数特征进行分析,得出该井强矿化带位置,判断了矿体延伸方向,并对深部隐伏盲矿进行分析,推测出井底附近无极化体存在。The IP in the well can be used to judge whether there is blind ore at the bottom of the well or near the well,and has achieved certain geological effects in determining the thickness,depth and extension direction of the ore bed.Induced polarization logging was carried out in ZK5003 borehole in a working area of Xunyang County,southern Shaanxi Province.Based on the analysis of electrical parameters of rock(Ore)in the working area,the position of strong mineralized zone in the well was obtained,the extension direction of the ore body was judged,and the blind blind ore in the deep part was analyzed,the existence of non-polarized body near the bottom of well is inferred.
