摘　　要：针对W5断块开发中存在的问题,开展储层构型研究,建立该区内各构型界面级次的识别和划分方法,理清了构型单元剩余油主控因素。河口坝和水下分流河道作为两种最主要的储油构型单元具有不同的剩余油分布特征,其砂体侧缘是剩余油相对富集区,不同沉积相的配置关系也影响剩余油的分布。该研究成果可用于指导W5断块下步井位调整。Aiming at the existing problems in the development of W5 fault block,the research of reservoir configuration was carried out to establish the identification and division method for all kinds of reservoir configuration interface level in this area,and sort out the main controlling factors of the remaining oil in configuration unit .The mouth bar and subaqueous distributary channel,which are the two types of most important storage configuration units,have different distribution char-acteristics of remaining oil.The sandbody edges of them are relative enrichment region of remaining oil.Various configura-tion relationships of sedimentary facies also affected the distribution of remaining oil.The study results can provide guid-ance for next-step adjustment of the well location in W5 fault block.
