摘要
东营凹陷南斜坡为具有多层含油层系、多种油气藏类型的复式油气聚集带,其中沙河街组四段上亚段是区内主要目的层段之一。根据岩性和电性资料,对区内沙四上亚段进行了详细的层序地层研究,共识别出7个较短期旋回、2个中期旋回。在连井剖面的层序地层对比基础上,建立了该区的地层格架,探讨了该区滩坝砂体的空间分布规律和沉积演化特征。
The oil measures and oil pools occur as a composite oil and gas accumulation zone on the southern slope of the Dongying depression, where the upper submember of the 4th member of the Shahejie Formation is believed to be one of the main target members, and may be divided into seven short-term cycles and two mid-term cycles on the basis of lithological and electrical data. The sequence stratigraphic correlation in well-tie sections made it possible to construct the regional stratigraphic framework and examine the spatial distribution of file beach and bar sand bodies and sedimentary facies evolution.
