摘　　要：本文以哈萨克斯坦ZAYSAN地区地震资料的叠前反演为例,介绍了AVO基本原理及处理、解释的基本方法。文中利用不同炮检距道集数据以及纵波、密度等测井资料,在可行性分析的基础上,拟合横波,再利用Zoeppritz方程近似式进行反演,获得了与岩性、含油气性相关的12种弹性参数,对储层物性及含油气性进行了综合判识。Taking the prestack inversion of seismic data in Kazakhstan ZAYSAN area as a case, the paper introduced AVO basic principle and processing and obtained basic approach of interpretation. Using different offsets gather data and P-wave and density logging data and on the basis of feasible analysis, the paper fitted S-wave and then used approximate formula of Zoeppritz equation to carry out inversion, acquiring 12 elastic parameters relative to lithology and oil/gas-bearing nature and carrying out integrative evaluation of physical property of reservoir and oil/gas-bearing nature.
