Abstract:On the basis of briefly introducing basic conception of converted wave and taking C-wave data practically acquired in Yongxing area as object, the paper carried out the study on such processing method as C-wave data purification, C-wave static corrections, sweeping of P-wave-to-S-wave velocity ratio, and better suppressed plane wave interference of C-wave in the area, acquired more precious C-wave statics and velocity and realized CCP (common converted point) stack by prestack time migration.
