Abstract | Due to lack of information about near-surface S-wave velocities, especially in the areas where near-surface structure and the subsurface are complex, receiver static corrections become one of the key steps in multi-component converted PS-wave data processing. In this paper, we first extract Rayleigh waves from the field shot records and obtain near-surface S-wave velocities based on the inversion of Rayleigh wave dispersion curves. The receiver statics of PS-waves are then calculated via P-wave statics. Finally, the method introduced in this paper is applied in 2D/3D seismic field data processing, which shows that S-wave statics are larger than P-wave statics and vary dramatically in the horizon directions; the PS-wave stack sections are improved after applying PS-wave statics. It can be concluded that this method is feasible for PS-wave static corrections. |
