基于基质矿物模量自适应提取横波速度反演方法
Keywords: 自适应提取,基质矿物模量,xu-white模型,横波速度反演
Abstract:
？鉴于运用xu-white模型时基质矿物模量(体积模量和剪切模量)取值较为困难,本文通过引入干岩石泊松比(σdry),借助gassmann-boit-geertsma方程,提出-种改进基质矿物体积模量的自适应提取方法。在提取基质矿物体积模量的同时,也提取基质矿物剪切模量,从而有效地解决了取值问题,使得利用xu-white模型准确反演横波速度成为可能。实际资料表明,基于基质矿物模量自适应提取的横波速度反演方法,不仅可以保证基质矿物模量的取值精度,而且能够提高反演横波速度的精度,反演与实测横波速度的相对误差不超过7%,误差均值仅为1.389%。
