| 摘 要： | 复电阻率法是上世纪70年代发展起来的一种激电分支方法，自提出伊始就受到了国内外学者的广泛关注.很多学者开展了复电阻率电磁场正演计算，但缺少对正演结果的深入分析.本文采用体积分方程法，进行了复电阻率模型的正演模拟，通过对正演结果分析，得出三维复电阻率体的电磁响应是由累积电荷，电磁感应和激电效应共同产生的，并总结了三种效应的电磁响应规律，为准确分析异常提供了依据. |

| Abstract: | The complex resistivity method is one of IP methods. It was put forward in the 1970s. Many experts have studied the method, but the result of electromagnetic field responses has not been analyzed in detail. In this paper, we first simulated some responses of the complex resistivity models by integral equation, then analyzed the results. At last, we deuced and summarized that the electromagnetic response of 3D complex resistivity is produced by charge effect, electromagnetic effect and IP effect. The results will be useful for practical analysis of complex electromagnetic survey. |
