PROCESSING SEISMIC DATA IN COMMON GROUP-CENTER GATHERS
摘要
<p>A method for processing seismic data. The method includes plotting a travel-time curve and one or more actual times that each seismic receiver receives one or more seismograms on a graph. The travel-time curve represents an approximate time that each seismic receiver in a seismic survey area receives the seismograms. The method may further include determining a residual static shift for each seismogram and using the residual static shift to estimate a time shift correction. The residual static shift represents a difference between an actual time in which a seismic receiver received a seismogram and a time on the travel-time curve that corresponds to the actual time. The time shift correction corrects a timing error in the time indicated by the travel-time curve.</p>
