Abstract：In order to improve seismic imaging quality, we propose in the paper a method for removing moveouts of azimuth anisotropy based on the difference theory, and put forward formulas for moveout corrections. Test results on both model and real data show that data resolution and signal-to-noise ratio have been significantly improved in both prestack gathers and stack sections.
