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 multicomponent 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.
