Abstract: TEM method is used to study the space distribution regularity of permafrost strata in order to offer the base for further research of the northeast natural gas hydrate prospective investigation. This method gets better geological result by using pseudoseismic interpretation imaging technology to inverse TEM field data to divide the reflect interface and electric level and then inferred the distribution of permafrost strata of Mohe region successfully. The inverse result shows that the permafrost strata of the south-north second measurement line developed well with large thickness, had certain continuity, and was consistent with the result of VES.

Key words: Mohe region, transient electromagnetic method, pseudo-seismic interpretation, permafrost strata
