【Abstract】 The paper introduced theoretic study and real application of Fourier finite-difference prestack depth migration which has an advantages of distortionless seismic wavefield and high-quality of imaging by processing of complicated Marmousi model. The processing results of 2-D seismic data in ZX area are also presented at same time. Comparing with that of Kirchhoff integration method, the results of Fourier finite-difference prestack depth migration is better in imaging and amplitude fidelity, but poor in computational efficiency.更多还原
