%X Anisotropic prestack depth migration becomes closer to perfection since after many years of research and development. In seismic processing, however, inaccurate parameters estimation of the media is the main reason for poor imaging quality. When the estimated parameters of VTI media are close to their real values, the residual curvature analysis modeling method of anisotropic migration velocity analysis based on wave equation is applicable to anisotropic and laterally varying media because it is not associated with the complex geological condition. We will obtain a velocity modeling by anisotropic migration velocity analysis with the common imaging gathers extracted from a migration result. Numerical experiments and field data show that this method could improve the quality of migration results and obtain a robust image of VTI.
