英文摘要We present a new redatuming technique based on the virtual surface, Rayleigh integral, and phase-shift method. Combining the redatuming technique with the pre-stack time migration results in a pre-stack time migration scheme and workflow which can be applied to the dataset acquired at the irregular surface. The resulting scheme can correctly model seismic wave propagation in the complex near surface, thus avoiding the errors related to static correction when high speed media are exposed on the surface. Moreover, we give a method to determine the reasonable velocity of virtual medium. No prescribed near surface velocity model, which is key for the conventional redatuming technique, is needed. Two synthetic datasets from models with and without low speed media near the surface are used to test the proposed scheme.
