本文通过对二次加密井高含水期综合治理方法的研究,阐述了改善二次加密井开发效果的作法和经验,提出了注水井改造和细分注水,努力增加差油层注水量,是改善二次加密井开发效果的重要手段。并提出采取补孔措施挖掘剩余油潜力,治理低产能井的方法,为二次加密井高含水后期开发提供了宝贵经验。 Based on the research on the comprehensive treatment of secondary well with high water cut, this paper expounds the practices and experiences of improving the secondary well, and proposes that the injection well should be rebuilt and subdivided, and efforts should be made to increase the amount of water injected into the poor reservoir. Secondary well development of an important means of effectiveness. And put forward the method of supplementing the hole to excavate the potential of residual oil and to control the low-productivity wells, which provided valuable experience for the later development of high-water cut-off wells.
