为了解决油田中后期含水不断增加，成本不断上升的问题，提出了处理开采后期的高含水油藏中水的分离与回注系统．通过对该系统的结构和工作原理介绍，分析了可行性，并与常规系统进行了比较，认为该系统可降低高含水油井采出的水量，减少举升成本及地面水处理装置的投资，节约成本，提高油井产量，对开采高含水油田在技术上和经济上是可行的．
In order to solve the problem of rising water content and rising cost in the middle and later stages of the oilfield, a separation and reinjection system was proposed to deal with the high water-cut reservoirs. By introducing the structure and working principle of the system, the feasibility is analyzed and compared with the conventional system. The system is considered to reduce the amount of water produced by the high-water-cut oil well, reduce the cost of lifting and the investment of surface water treatment equipment, and save Costs and increased well production are technically and economically viable for the exploitation of high water-cut oil fields.
