Summary One-way wave equation (OWE) method has played an important role in the seismic imaging history, especially for high resolution migration. Among the different OWE methods, phase shift plus interpolation (PSPI) method is very accurate as long as we choose enough reference velocities. In this abstract, we modify Bagaini’s (1995) algorithm and use GPU/CPU collaborative parallel computing technology to accelerate the algorithm. Besides, we interpolate the wave-fields before image to remove the imaging alias. The field data example from jilin oil field proves the efficiency of the algorithm.
