摘要: 大民屯凹陷古近纪可划分为3个二级层序,分别对应于沙四段—沙三段(SQ1)、沙一段(SQ2)、东营组(SQ3),其中沉积层序SQ1生、储、盖层配置关系好,具有优越的油气成藏条件。西斜坡沉积层序SQ1的低位体系域砂砾岩体是近年来岩性油藏勘探的重点目标。在等时地层格架约束下,运用具有预测意义的地震属性提取技术进行沉积相研究,运用多属性岩性地震反演技术对大套砂砾岩体中的薄储层进行识别和刻画,在勘探实践中获得了良好的效果。

Abstract: Paleogene in Damintun sag could be divided into three second-order sequences which correspond to SQ1, SQ2 and SQ3. Among them, SQ1 enjoys a good distribution of source bed, reservoir and cover rock, and it has an excellent oil deposition condition. So the SQ1 becomes the focus of oil exploration in recent years. Constrained by the isochronal stratigraphic framework, seismic attribute extraction is used to study sedimentary facies. Multi-attribute lithological seismic inversion is employed to identify and describe the thin reservoir in sandstone body and good results are obtained
Key words: sequence stratigraphy, glutenite body, seismic attribute extraction, multi-attribute lithological seismic inversion, Damintun sag
