摘　　要：飞雁滩油田注聚区 ,在综合含水 86 .1%时投入聚合物驱油 ,是胜利油田有限公司投入聚合物驱含水最低的单元。经过一年多的矿场实施 ,已见到较好的增油降水效果 ,日产油由 6 5 2t/d上升到 75 8t/d ,综合含水降至 79.9% ,累计增油 2 .2× 10 4t。目前处于见效阶段 ,并体现了聚合物驱前期的注采动态特征。通过注聚实践研究认为 ,对注聚井分类管理、平衡油井平面采液强度 ,是今后进一步改善聚合物驱效果的重要技术措施。The area within Feiyantan oilfield was under polymer injection when the total water cut reached 86.1%. As such the area claims the lowest water cut among all the areas put into polymer injection in Shengli oilfield so far. A good effect of increased oil production and decreased water cut appears after the polymer flooding has been carried out over one year. Oil production increases from 652?t/d to 758?t/d, while total water cut decreases from 86.1% to 79.9%. And a cumulative incremental production of 2.2×10 4?t has been obtained. Currently the character of early stage flooding production performance is apparent. The practiceand research show that the important measures to improve polymer flooding effect in the coming years should be differential management of the injection production wells, and a balanced recovery of liquids from the wells.
