On the basis of phase shift wave field extrapolated method, this paper method was formed by fusion of split-step Fourier transform and finite difference compensating algorithm to promote the algorithm stability, and surely make progress in energy compensation, fidelity and raising resolution. The processing method is presenting advantage to characterize lithologic boundary in Y1 area. Good results have been obtained.
