摘　　要：孤东油田七区中注聚后部分油井见聚浓度高,注聚过程中层间矛盾突出.为此,应用聚和物堵水调剖决策系统对目前七区中注聚后的窜聚井进行了综合治理,对高见聚油井采取了干灰阻聚措施.通过对注聚井的防窜及油井阻聚,取得了明显的效果.最后对整体堵水调剖效果进行了评价,为同类油藏的堵水防窜提供了参考模式.In the studied zone, the concentration of polymer in some oil wells is high in the later stage of polymer displacement process and the interzonal channeling is serious in the polymer displacement process. For this reason, these channeling wells in this area are harnessed using polymer water-plugging - profile-control decision system. The channeling preventing measures of injecting wells and the polymer blocking measures of oil wells are implemented and a good result is achieved. The whole result of the water-plugging - prof ile-control of this area is evaluated, and the evaluation result in this paper can provide reference for the water-plugging and channeling-preventing of the same kinds of oil reservoirs.
