摘要
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 in-version.
