摘要
根据EM-37瞬变电磁系统中心感应回线装置下的野外实测数据,并结合前人的研究成果,详细讨论了极化体电阻率与埋深、发射线框尺寸与位置对IP效应的影响规律;此外,在实践中发现了IP效应的二次反号现象,总结了一套如何削弱或消除瞬变电磁测量中这种激电效应的实用方法技术。
おsing the observed dB/dt data by EM37 transient electromagnetic system in centralinduced loop survey and the previous researching results, this paper has demonstrated inducedpolarization effects in negative TEM response. These effects have approximate negative exponential decays which are often observed. It is also possible by using a simple approach to remove negative polarization effects, which is of practical value.
