Abstract:In order to remove the residual time shifts resulting from the variations of weathering velocity and weathering thickness,we developed the PRSTC module for making residual static correction of seismic data before NMO correction, Thus, the residual static corrections can be calculated using original seismic waveform without stretch in the case of incorrect velocity and dipping reflectors so that good data can be provided for velocity analysis, NMO correction, stacking and prestaeking processing.Just like the field static correction, this module (PRSTC) is also essential to seismic data processing.The practical application shows that this module can fulfil the effect and speed requirements in seismic data processing, thus enriching seismic processing module family.
