摘要
转换波叠后剖面与纵波叠后剖面之间在分辨能力、剖面特征上还存在着较大的差异,为了使转换波剖面能尽量地与纵波剖面相匹配,采用反Q滤波方法,适当提高叠后转换波剖面的分辨能力,调整其相位、振幅、频率特征,以满足转换波和纵波联合解释和反演的需求。实际效果表明,该方法为后续纵波转换波联合解释及反演工作提供了条件。
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.
