摘要
延9油层是靖边油田东坑大阳湾地区的主力产层.将沉积体系、低幅构造、古地貌等作为一个有机的整体,对靖边油田东坑大阳湾地区的油藏控制因素进行重点分析.结果表明,古地貌控制着东坑大阳湾地区延9沉积相的展布及低幅构造的形成,并通过与低幅构造、沉积砂体的良好配置,控制着油藏的分布.
The Y-9 reservoir is the main production layer in Dayangwan area of Jingbian Oilfield.Taking the sedimentary system,low-amplitude structure and paleogeomorphology as an organic whole,the paper focuses on the controlling factors of reservoir.The results show that the paleogeomorphology controls the distribution of sedimentary facies and formation of low-amplitude structure of Y-9 reservoir,and also the distribution of reservoir through the favorable accumulation disposition with low-amplitude structure and sedimentary sand bodies.
