摘要
AVO技术是Zoeppritz方程在地球物理勘探中的重要应用.本文在回顾Zoeppritz方程及其简化形式的基础上对AVO技术的最近发展进行了介绍.AVO技术是利用地震资料研究岩性和含油气性不可或缺的工具.近年来AVO理论和技术发展呈现新的方向,主要表现在以下几个方面:利用多波多分量地震数据进行纵波、横波、转换波的AVO分析,预测储层的含气性和检测裂缝发育;利用AVO技术定量表征岩性和储层的流体性质;进行3DAVO分析研究等.本文对此进行了介绍,并对AVO技术的前景进行了展望.
AVO technique is an important application of Zoeppritz's equation in geophysical exploration.After brief reviewing Zoeppritz's equation and its simplified equations,this paper introduces recent development of AVO technique.AVO technique is a vital tool of utilizing seismic data to explore lithology and hydrocarbon.Modern AVO theory and technique present new aspects such as:using P-wave,S-wave and converted wave AVO analysis of multi-component seismic data to predict gas and detect fracture;using AVO technique to characterize lithology and fluid character quantitatively,to progress 3D AVO analysis,and so on.This paper also prospects the future development of AVO technique.
