摘要
详细论述了AVO非线性反演方法的原理、反演中目标函数的构造以及海色矩阵的计算 ,获得了较精确的含气砂岩的泊松比值 ,直接检测了气层。应用实例表明 ,AVO非线性反演是一种求取精确解的方法 。
This paper describes in detail the principle of non-linear inversion on AVO responses as well as the construction of objective function and calculation of Hesse matrix which are all used in the inversion. Accurate values of Poisson's ratio are obtained and gas reservoirs are detected directly by using the proposed method. Real examples show that the proposed AVO non-linear inversion method results in exact solutions and has broad prospects for application.
