摘　　要：对地震属性的定义、研究历史和发展现状做了概要叙述;对当前在用的地震属性做了分类,给出了其拾取方法。介绍了三维储层表征平面动画显示、地震属性分析与成因地层学综合、谱分解属性检测储层品质等方面的技术。指出,在地震属性定量解释中,用实验数据导出法建立的关系是实现地震属性定量解释的必要步骤;总结地震属性分析的应用经验,找准与储层岩石物性相关的地震属性是成功解释的关键;地震属性分析中存在陷阱,使用时要引起注意。The seismic attributes definition, research histroy and development status are briefly described. The seismic at-tributes are classified and extraction methods are also presented in it. Several aspects are introduced, such as plane ani-mation displaying 3D reservoir characteristics, 3D seismic image, integrating seismic attribute analysis with geneticgeology, spectral factorization detection applying to reservoir quality. Pointing out that relationships derived from ex-periment data are necessary steps to realize quantitatively interpreting seismic attribute, application experience forseismic attribute analysis is summarized, and precisely extracting seismic attribute related to physical characteristics ofreservoir rock is a key of successful interpretation. It should pay a attention to seismic attribute analysis pitfall.
