摘　　要：利用井中激电地—井测量方式可判断井底、井旁是否有盲矿,利用井—地充电剖面测量方式可判断矿体产状、走向。在内蒙古北窝铺铜矿床勘查中,通过井中激电测量圈定了高极化异常段并确定为矿化蚀变带引起,推断矿体为NE走向,倾向SE。经钻孔验证推断结果正确。此次工作表明井中激电可以指导钻孔工程,减少勘查投入。In-well IP is one of the effective means to explore deep sulfide-type metal ore.In the well,the electric field-well method is used to find the bottom of the well and the blind mine near the well;in the well,the electric well-ground method is used to determine the ore body s direction and judge its occurrence.The exploration examples of the Beiwopu copper deposit in Inner Mongolia indicate that the ground-well IP measurement corresponds to high polarization anomalies in the pyrite-rich and brass mineralization-enriched rock sections;the well-ground charging method is used to measure the occurrence of ore bodies.Judging,retrieving the direction of the ore body,guiding the drilling project,reducing the investment in exploration,and achieving A better prospecting effect.
