摘 要：The transversely isotropic(TI)media approximation is commonly applied to assist in the processing of seismic data acquired in sedimentary *** on anisotropic kinematic and dynamic ray tracing systems,a P-wave Gaussian beam prestack depth migration(GB-PSDM)method for TI media is introduced in this *** imaging principle of anisotropic GB-PSDM and the corresponding migration parameters are presented on the basis of the GB-PSDM method in isotropic *** of synthetic and field seismic data show that the method is an accurate and efficient anisotropic prestack depth migration method in TI media.
