| 英文摘要 | The multi-channel transient electromagnetic (MTEM) is a new exploration method developed in recent years. The data acquisition mode of MTEM is similar to that of seismic methods so that pseudo-seismic interpretation technology is suitable for MTEM data. It is significant to research pseudo-seismic wavefield extracting technology for MTEM data. Based on the singular value decomposition (SVD) method and preconditioned regularized conjugate gradient method, we propose a correlation stacking method to extract pseudo-seismic wavefield of MTEM data. We firstly extract the pseudo-seismic wavefield from whole-time-domain MTEM data with the preconditioned regularized conjugate gradient method, then extract the pseudo seismic wavefield from the data of each time quantum determined with the same method. Finally, this method stacks the pseudo-seismic wavefield data according to their correlations, regarding the stacking result as the final extracting result. Comparison shows that the pseudo-seismic wavefield extracted from the measured MTEM data with the correlation stacking method is smoother than that of the SVD method or the preconditioned regularized conjugate gradient method. Besides, the anti-interference ability of this new method is stronger. |
