Abstract: On the basis of the magnetotelluric curve comparison method inversion, we introduce phase information into the inversion procedure. It means inserting phase correction parameter into apparent resistivity correction element during the inversion, which makes the program more rapid and the procedure more robust. Comparing with other inversion methods of model research, the result of using curve comparision method with phase information can represent the electrical property distribution of the model correctly, and can be used as the initial model of multi-dimension inversion.
