英文摘要We present a pre stack time migration scheme and workflow that can image land seismic data without field statics corrections. The scheme uses a "spread" imaging method. The travel times and amplitudes for computing the impulse response of each trace are obtained using the stationary phase theory. This results in a table-driven migration algorithm. The proposed scheme. can update the velocity model for both the stack velocities and near surface velocities with respect to the flats of the events. We also adaptively determine migration aperture according to the dips of the imaging structures. This reduces the computational cost and suppresses the migration noises. A synthetic dataset, which is generated using acoustic finite-difference for a rift subsidence basin including 2-D irregular surface, is used to demonstrate the scheme.
