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.

Key words: third-order sequence, lithologic reservoirs, Jabung block, South Sumatra Basin
