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652 t/d上升到758 t/d,综合含水降至79.9%,累计增油2.2×104t。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。

Abstract:

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. 2×104t 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.

Key words: sandstone reservoir, polymer flooding, injection-production performance, example
