LI Xiu1,XUE Guo-qiang2,GUO Wen-bo3(1.School of Geology and Survey Engineering,Chang,An University,Xi,an 710054,China;2.Institute of Geology and Geophysics,Chinese Academy of Sciences,Beijing 100029,China;3.School of Electronic and Information Engineering,Xi,an Jiaotong University,Xi,an 710049,China)  
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.
