弹性波阻抗反演是近年来地震反演技术的一个“亮点”，也是反演研究的热点，是一种结合了常规声阻抗反演和叠前AVO 反演的地震反演技术。它利用不同炮检距道集数据及横波、纵波、密度等测井资料，联合反演出与岩性、含油气性相关的多种弹性参数，综合判别储层物性及含油气性。文中对叠前弹性波阻抗反演的基本原理及方法作了简要论述，并给出了该方法的应用实例。

The elastic wave impedance inversion is a “bright point” in the seismic inversion technique in recent years, and alsoa “hot point” in the inversion research. Elastic wave impedance inversion is a seismic inversion technique which combines conventional acoustic impedance inversion with AVO inversion. It uses different offset gathers data and S- wave、P- wave and density data to carry out joint inversion of elastic parameters related to lithologies and oil/gasbearing ability, and determine the reservoir properties and oil-bearing ability. The basic principle and method of the pre-stack elastic wave impedance inversion are briefly expounded, and the application case is given.
