英文摘要We present a 3D prestack time migration scheme and workflow that can image land seismic data without datum static corrections. The scheme mimics the influences of the near-surface and overlay on wave propagation using two equivalent velocities. As a result, it is not necessary for wave path to be vertical incidence in the near-surface, as in conventional static corrections. This leads to the proposed scheme which can handle the more complex surface cases, such as the exposure of high velocity in the near-surface. The proposed scheme can update the two equivalent velocities with respect to the flats and consistency of the events. A synthetic 3D dataset and a field 3D dataset without datum static corrections are used to demonstrate the scheme and the workflow.
