Abstract
This paper briefly introduces the developing trend of wave equation prestack depth migration technolo-
gy, discuses P-gather wave equation velocity analysis technology, and presents the formula of common-azimuth
wave equation prestack depth migration methed.On super computer Shenwei 1, we realized common-azimuth
wave equation prestack depth migration on 130km~2 3-D seismic data. The migrated results verified the correctness
of the method, and showed the usefulness of the method in imaging complex structures.
