摘　　要：地震弹性属性参数与地层岩性密切相关,它的变化能够比较真实地反映出地层岩性的变化,因此,可以根据弹性属性参数及其变化,较直观、可靠地评价储层。在研究地震弹性属性参数基本意义的基础上,阐述了含油气储层的弹性参数的基本特征,探索了典型的含油气弹性参数属性剖面的解释方法和准则,并对国内外典型地震弹性参数属性剖面进行了解释,得出了有益的结论。该技术为隐蔽性岩性油气藏的勘探开发提供了新的技术支持,能够降低勘探开发风险。Elastic parameters of a reservoir are closely correlated with the lithology of a stratum. Their variations reveal the changes of lithology of the stratum. Therefore elastic parameters of a reservoir can be used to accurately evaluate the reservoir. Based on the investigation of the meanings of different elastic parameters and the characteristics of elastic parameters for hydrocarbon-bearing reservoirs, this paper studied the interpretation techniques of elastic attribute sections, and demonstrated them with real data examples both from home and abroad. The conclusions could be applied to the exploration and production of subtle lithological reservoirs.
