摘　　要：从与常规井对比、完井方式、开发区块、措施效果四个方面分析了吴起油田延10底水油藏开发效果。运用递减法预测了每口井15年的产液、产油和含水,发现完井方式对油井含水变化有很大影响。对异常水平井的补孔增产效果进行了分析,发现如果水平井底水上窜水淹,由于底水沿水平段一线整体上升,预留水平段打开也会很快水淹。The development effect of bottom water reservoir in Yan10 of Wuqi oilfield was analyzed from four aspects of comparison with conventional wells, well completion mode, development block and measure effect. The decline method was used to predict the production of fluid, oil and water in each well for 15 years. It was found that if the bottom-water upward breakthrough and flooding appeared in the horizontal well, the reserved horizontal section would soon be flooded because the bottom water rose along the first line of the horizontal section as a whole;The completion method had a great influence on the water cut of the well.
