研究提高注水油田排液量的问题,有助于挖掘油田潜力,延长油田高产稳产期,提高油田采收率。对比了用一维二相、二维二相、生产资料,三种方法预测油田开发过程中采油、采液指数变化的差异;分析了不同类型油田采油、采液指数的交化规律,水驱前缘含水饱和度及耗水量的差异;指出不同类型油田提高油田排液量的目标和方法应是不同的,提高排液量的开采特征和经济效益也不相同。文中还论述了在提高排液量的同时,必须注意提高注入水利用率等问题。
Research to improve the flooding of waterflooding oilfield problems, help to tap the potential of the oil field, prolong the production of high production stability, improve oil recovery. The differences between the two methods of one-dimensional two-phase, two-phase two-phase and production materials are compared. The differences of the oil production and liquid production index in oilfield development are predicted. The differences of water saturation and water consumption in the frontal areas are pointed out. The objectives and methods for improving the discharge of oilfields in different types of oilfields are pointed out. The mining characteristics and economic benefits of increasing drainage volume are also different. The article also discusses the issue of improving drainage capacity while paying attention to improving water injection rate and other issues.
