摘要	As the depth migration of multi-component seismic data can obtain better images of the subsurface structures with multi-wave information in seismic records, an effective multi-component Gaussian beam migration method is presented in this paper. Firstly, a detailed numerical analysis on the local slant stack is carried out, which demonstrates that the Gaussian beam migration method has good directionality and computational efficiency through decomposing seismic records into different outgoing directional local plane waves. Then two different Gaussian beam prestack depth migration algorithms are presented, corresponding to the PP-and PS-waves, after a wavefield separation is effected with an affine coordinate system transform. Finally, tests of synthetic and field seismic data show that the method introduced above would be an accurate and efficient prestack depth migration alternative for multi-component seismic data.
