中文摘要：
瞬变电磁法是工程地球物理勘察中应用较多的一种勘探方法之一，瞬变电磁法拟地震成像方法研究是当前电磁探测理论与应用研究的热门．文中详细叙述了瞬变电磁法拟地震成像的两种不同思路，一种是建立时间-频率转换经验公式，把TEM数据转换成平面波数据，借鉴大地电磁法拟地震解释思路进行成像，另一种是通过积分变换，把扩散场变成虚拟波场，把电磁衰减信号变成拟地震子波，然后按照地震解释法进行解释，并分析了各自存在的的问题．指出下一步研究的方向．
英文摘要：
Transient electromagnetic method （TEM） is one of popular used method in engineering and geophysical exploration, the study of TEM pseudo-seismic imaging is the popular subject in the theory and application of electromagnetic detecting. In this paper, we introduce two ways of TEM pseudo-seismic imaging, one way is transforming TEM data to plane wave data, and finishing TEM pseudo-seismic imaging basing on MT pseudo-seismic method. Another way is transforming diffusion field into pseudo-wave field, and transforming electromagnetic decay signal into pseudo-seismic wavelet, and finish TEM pseudo-seismic imaging basing on seismic method . We analyses the existing problem in the two imaging way and guide the direction of next study.
