摘要
针对五里湾长_6油藏已经进入中含水期,相渗逐步发生变化,水驱油效率降低,为延缓含水上升速度,提高最终采收率,开展了以调剖和驱油技术以及复合调驱技术提高采收率的研究,并针对调驱技术及其应用中存在的问题和难点,借助系统的理论分析和多种实验技术,重点突破,探索出长庆油田采油三厂注水开发油田提高采收率的有效方法和途径,在五里湾一区开展了一口井的现场试验,试验效果良好。
Being aimed at the phenomen on of Wuliwan chang 6 reservoir has entered medium water-cut stage, gradual change in multiphase flow, reduce the efficiency of Water flooding, to slow rate of water rise, improve the ultimate recovery, carried out the Profile control and flooding technology ,and composite oil displacement technique study of enhanced oil recovery. It aims at that the problems and difficulties in oil displacement technique and its application ,with systematic theoretical analysis and a variety of experimental techniques, breakthrough at key points, explore the effective ways and means of oil production Plant3 of Changqing Oilfield Company in water injection to enhance oil recovery .Through the reservoir description, optimization of well selection, carried out a well field test in wuliwan area, well test results.
