多波多层AVO数据反演

作为笔者提出的Ｚｏｅｐｒｉｔｚ方程级数表达式的直接应用，本文讨论了临界角内ＡＶＯ的信息是，提出了一种多波多层ＡＶＯ反演方法，由于采用了Ｚｏｐｐｒｉｔｚ方程级数表达式解析计算反演中是Ｊａｃｏｂｉ矩阵，因而使ＡＶＯ反演的速度和精度均有改善。文中用理论模型分析了多层Ｐ－Ｐ波ＡＶＯ反演，多层Ｐ－Ｐ波和Ｐ－ＳＶ波联合ＡＶＯ反演、Ｐ－Ｐ波和Ｐ－ＳＶ波循环迭代ＡＶＯ反演方法，并对野外实际资料进行了计算，取得了一

Multiwave multilayer AVO inversion

By using Yang Shaoguo's power series expression of Zoeppritz's equation, the authors analyse AVO information content in the critical angle, and put forward multiwave multilayer AVO inversion- AVO inversion is speeded and improVed because the series expression of Zoeppritz's equation is used to compute Jacobi matrix in inversion. Theoretical models are adopted to analyse multilayer P-P wave AVO inversion, joint multilayer AVO inversion of P-P and P-SV waves and sequentially iterative AVO inversion of P-P and P-SV waves- The computation of raw data was done to bring quite good result.
