| 摘 要： | 沉积密集段作为层序地层学理论中的一个重要概念，它控制着盆地生油岩层的分布和厚度。为了更好地研究生储盖组合关系，预测隐蔽油气藏，利用层序地层分析的基本原理和方法，对惠民凹陷进行了层序地层学研究，将其下第三系沙河街组二、三、四亚段划分为３种层序类型，确定出断陷初期型、强断陷期型和断陷后期型３种类型沉积密集段，每一层序又可进一步划分成低水位体系域（ＬＳＴ）、湖侵体系域（ＴＳＴ）、高水位体系域（ＨＳＴ）和下降体系域（ＦＳＳＴ）。不同类型的沉积密集段可控制着不同的生油岩层的厚度和油气资源储量

| Abstract: | Huimin depression is a terrestrial rift subsidence basin. In order to find out the relation of the source, reservoir and seal rock, a research of sequence stratigraphy in Huimin depression has been done. The result of the study indicates that the 2,3 and 4 submembers of Shahejie formation of lower Tertiary can be divided into three kinds of sequences and formed three kinds of condensed sections. The different condensed section will influence the abundance of source rock and the resources, and every condensed section controls the distribution and the thickness of the source rock. |
