摘要
电法工作组为配合内蒙某普查工作，先期开展激电中梯剖面，发现北部60度走向的低阻带状异常，随之布置激电测深剖面进行断面查证，后期确定钻孔位置并完成325米钻探。本文通过岩芯标本测孔取得的激电参数，与同点位激电测深数据对比，简要说明在相对低阻区激电测深与深度的关系，以及真激电参数和视激电参数的比例，论述激电测深与岩芯测孔对比的若干问题，总结激电参数在深度方面的特点。
Abstract
One electrical survey workgroup launched IP sections that discover a low resistivity anomaly zone which lies at an angle of about 60 degrees in the north with central gradient array method at first for coordinate with the general investigation in Nei Monggol. After that an IP sounding section was assigned for investigating & verifying and finally located the position as well as completed an exploration drilling which 325 meters depth. This article schematic illustrate the relationship between IP sounding and depth in the range of relative low resistivity , and the proportion of true IP parameters to apparent IP parameters, beside expound several problems of correlation between IP sounding and core of drill hole survey(CDHS) as well as summarize the characteristics of IP parameters on depth by means of the correlation IP parameters between CDHS and IP sounding.
