P-SV转换波积分DMO方法研究及应用

本文从纵波ＤＭＯ原理出发，提出一种Ｐ－ＳＶ转换波积分ＤＭＯ方法。该方法依据文中导出的Ｆ－Ｋ域转换波ＤＭＯ算法的积分形式进行振幅、相位校正，同常规转换波水平叠加相比能地改善叠加效果，更好地解决ＣＭＰ道集内共转换点发散问题。理论模型和实际资料处理结果表明，该方法是一种较理想，实用的转换波ＤＭＯ处理方法。

Study and application of the P-SV wave integral DMO method

Starting from the P-wave DMO principle, we put forward a P-SV wave integral DMO method .On the basis of the integral form of the P-SV wave DMO algorithm in F-K domain derived in the paper, the amphtude and pbase corrections are made, Compared with the conventional P-SV wave horizontal stacking, the method can obviously improve the stacking result and better solve the divergence problem of common converted points in CMP gathers. Theoretical models and real data processing results show that the method is satisfactory and practical for the DMO processing of P-SV wave.
