地层岩性油气藏地震属性的研究和应用——以准噶尔盆地永1井区为例

Research and application of seismic attributions of formation lithology hydrocarbon reservoirs——in the Yong 1 area as an example

本文以准噶尔盆地永1井区为例,在详细分析了目的层的地震和测井特征后,针对砂泥岩薄互层的叠后地震属性进行剖析.分析了不同地震属性在研究区的应用情况,同时对产生这种情况的原因进行了分析;本文中的叠后地震属性主要分层位属性和体积属性两类进行研究,在地层岩性油气藏的研究中起到了重要作用,在实际应用中取得了一定的成果.

This article analyzes the seismic attributions of post-stack seismic data based in the Yong 1 area, Jungar basin. Seismic and logging characters are analyzed in detail. We also analyze the application cases of different seismic attributions in the area. At the same time, we interpret the reason for these cases. The post-stack seismic attributions are classified into two types （horizon attribution and volume attribution）, which play an important role in the research of lithologic hydrocarbon reservoirs and acquired much success in the practical application.
