%X The Dongpu depression is a faulted basin with versatile depositional environment,  broken fault-blocks and complicated structures. Its local structure is controlled by faults. There are major lateral velocity alternations because of different buried depths of contemporaneous strata in the two sides of faults. But time migration is unable to work out this problem, so anisotropic pre-stack depth migration has been applied to this area, and high density velocity analysis is ombined with acoustic logging data. The results show coincidence of seismic and drilling with anisotropy PSDM.
