摘要
弹性波阻抗 (EI)技术是一种结合了常规声波阻抗 (AI)反演和 AVO反演技术的方法 ,可以利用远炮检距地震角度叠加数据进行波阻抗的反演工作。通过对现有的几种弹性波阻抗计算方法的分析 ,本文提出了一种结合相邻层速度和密度的变化规律、并基于范数动态可调的弹性波阻抗计算的改进方法 ,结合典型岩性参数模型的计算 。
Elastic wave impedance technique is a method combining ordinary acoustic wave impedance inversion with AVO inversion,which can use seismic angular stack data in far offset for inversion of wave impedance.Analyzing presently proposed several calculation tools of elastic wave impedance, the paper presented a modified method that combined with variated rule of adjacent velocity and density and with norm dynamic adjuctable etastic wave impedance calculation and illustrated the effectiveness of the method by calculation of models with typical lithologic parameters.
