【摘要】 作为笔者提出的Zoeppritz方程级数表达式的直接应用，本文讨论了临界角内AVO的信息量，提出了一种多波多层AVO反演方法。由于采用了Zoeppritz方程级数表达式解析计算反演中的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液循环迭代AVO反演方法，并对野外实际资料进行了计算，取得了一定的效果。更多还原

【Abstract】 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.更多还原
