Abstract

The data acquisition mode of Multi-channel transient electromagnetic method (MTEM) is similar to that of seismic method, it is significant to research pseudo-seismic wave-field extraction technology for MTEM data. Basing on singular value decomposition method and regularized method, we propose correlation stacking method to extract pseudo-seismic wavefield of MTEM data. Firstly extracting pseudo-seismic wave-field of whole-time-domain MTEM data with regularized method, then extracting pseudo-seismic wavefield of each time quantum determined with the same method. Finally, stacking the pseudo-seismic wavefield data according to their correlation, and regard the stacked result as the final extraction result. The extraction result of measured MTEM data with correlation stacking method is more smooth than that of singular value decomposition method and regularized method.
