Transverse wave static correction method and system

The invention provides a transverse wave static correction method and system. The transverse wave static correction method comprises the steps of obtaining p set data according to original shot gatherdata; obtaining model trace data according to the p set data; selecting a plurality of first time windows according to transverse wave data in the p-set data; obtaining p-set data and model trace data in each first time window and performing mutual correlation to obtain a first time shift amount of each first time window, thereby obtaining a second time shift amount; correcting the p set data according to the second time shift amount, and obtaining new shot set data according to the corrected p set data; selecting a plurality of second time windows according to converted wave data in the newshot gather data; obtaining original shot gather data and new shot gather data in each second time window and performing cross-correlation to obtain a third time shift amount of each second time window so as to obtain a fourth
