Li Guofa, Mou Yongguang, Dai Dong, Guan Limei, Liang Qi, Zhang Wubin.Application of Arbitrary V (z) DMO Processing in Deep Seismic Data Processing of Dagang Petroleum Geophysical Prospecting, 2 0 0 1, 36 (6): 6 6 Based on the analysis of DMO and dipole decomposition DMO in normal speed frequency domain, this paper discussed some arbitrary V (z) DMO. Compared with normal DMO, arbitrary V (z) DMO is closer to the actual geological conditions. Its impulse response is no longer a simple SMIL E ellipse. Its response is difficult to express analytically according to the velocity field. The result of seismic data processing in Dagang shows that the arbitrary V (z) DMO method can adapt to the large change of velocity, so that a better imaging effect can be obtained for the extended long-angle diffraction and reflection.
