Abstract Based on anisotropic kinematic and dynamic ray tracing systems, a P-wave Gaussian beam prestack depth migration method for VTI media is introduced in this paper. The imaging principle of anisotropic Gaussian beam prestack depth migration is presented on the basis of Gaussian beam prestack depth migration algorithm in isotropic media. For horizontally layered VTI media model, the influence of anisotropic parameters on Gaussian beam prestack depth migration is illustrated. Tests of multi-layer shale model and SEG/Hess model show that the proposed method is an accurate and efficient anisotropic prestack depth migration approach in VTI media.

Key words： VTI media anisotropy ray tracing Gaussian beam prestack depth migration
