Abstract: Converted PS-wave exploration technology has been developed rapidly, but there is still big difference in resolution and profile characteristics with PS-wave and P-wave profile. In order to match the PS-wave profile with P-wave profile as much as possible, we use the inverse Q filtering method to increase the resolution appropriately in stack converted PS-wave profile after adjusting its phase, amplitude and frequency characteristics, and achieved good results, provided the conditions for the follow-up converted PS-wave and P-wave joint interpretation or inversion.
