Replacing velocity analysis of interval velocity

摘要

Through the analysis of common-used static correction method, it is considered that replacing complex interval velocity with the velocity of underlying medium and removing the effects of complex formation on seismic data processing could improve the precision of velocity analysis. For the CMP gathers, the prestack double square root operator could be used to continue and strip layer by layer in common midpointhalf offset. The velocity analysis method presented in this paper is to remove the effects of complex formation on seismic velocity analysis. The theoretical model computation indicates that this method is feasible.
