吉77块经过几十年的开发,地层形成了大孔道,注入水进入地层后沿着大孔道窜流,导致注入水的无效循环,部分油井出现水淹、水窜、高含水现象,而其它油井注水又跟不上,导致地层能量不足,产量递减快.经过调剖后,虽然封堵了部分层位,但是又不可避免的集中出现了新的高吸水层,含水上升的问题仍然没有得到很好的解决.为实现稳油控水目标开展了多轮次调剖,先调剖堵水再调驱增油等改造措施,达到了一定的效果.

After decades of development,the strata formed large pores,injecting water channels along large channels into the formation,leading to invalidity cycle of injected water,and some oil wells appear flooding,water channeling,high water phenomenon,and water injection can not keep up in other oil, leading to the formation energy none sufficient,the production decline rapidly.After profile control, although the blocking part layer,but it is inevitable concentration appeared a new high water-absorbing layer concentration,water cut rising problem is still not solved very well.In order to achieve the goal of stabilizing oil production and controlling water multi-round profile control is conducted,the first water plugging and profile control and other reform measures to adjust the flooding,achieving a certain effect.
