Based on the basic principle of magnetotelluric static migration and the processing of large quantities of measured data,this paper puts forward for suppressing static migration-the standardized correction method for static migration,which is more effective than the traditional static correction method.The kernel of this technique is the utilization of lithologic electrical parameters and the surface or shallow strata at the positions of measuring points to standardize the first branch of the apparent resistivity curve,and the use of interactive visualized static migration software to correct the apparent resistivity curve.Practice shows that this method is a fairly ideal technique for static migration correction.
