摘要/Abstract

摘要： 为了提高特高含水期点坝储层剩余油采收率，以胜利油区孤东油田七区西为例，在曲流河点坝储层精细构型解剖的基础上，利用基于构型单元的侧积体建模方法建立起点坝精细构型地质模型，利用油藏数值模拟方法预测曲流河点坝储层剩余油分布特征，揭示其主控因素，建立分布模式。研究表明，曲流河点坝储层中剩余油的分布受到储层构型、射孔层位和注采方向等多个地质及开发因素的综合影响，在这些因素综合作用下的剩余油分布模式可归纳为5种，即上注上采型、下注上采型、合注合采型、上注下采型、下注下采型，这5种类型剩余油富集程度依次增高。综合对比5种类型的剩余油分布模式认为，逆侧积夹层倾向注水条件下油水井间的储层中上部位置是点坝储层剩余油的有利富集区，水平井可以改善曲流河点坝储层水驱开发效果，提高剩余油采收率。

Abstract: In order to enhance the remaining oil recovery of point bar reservoir in the extra-high water cut stage, taking the west 7th block of Gudong Oilfield in Shengli Oilfield as a case,based on fine reservoir architecture analysis of meandering river point bar reservoir,lateral accretion body modeling method based on reservoir architecture unit was used to establish a reservoir architecture model,and then numerical simulation technology was used to predict the remaining oil distribution and analyze the main controlling factors. The results show that reservoir architecture,performation intervals and injection direction have great implications for the remaining oil distribution in meandering point bar reservoir. Five patterns of remaining oil were summed up,including upper injection-upper production,lower injection-upper production,commingling production-injection,upper injection-lower production and lower injection-lower production. The enrichment degree of these five patterns of remaining oil is increasing in turn. According to comprehensive comparison of the five patterns of remaining oil, the favorable enrichment area of remaining oil is located in the upper reservoir where the injection direction is opposite to the dip direction of lateral accretion beddings. It is considered that investing horizontal well is an effective adjustment measure to improve the development effect of meandering river point bar reservoir, which can enhance the recovery of remaining oil.
