目的：针对目前国内大多数注水开发油田已进入高含水采油期的实际情况，分析不同类型油田的采液动态及耗水量特征，研究提高排液量与稳油控水的关系。方法：根据无固次采液（油）指数把注水开发油田分成不同类型。结果：研究得出了辽河油区三种不同类型的油田在开发过程中采液（油）指数的变化规律。结论：根据不同类型油田采液（油）指数的变化规律，采取相应的稳油控水措施，可为中高含水期实现油田稳产或减缓递减提供简便实用的方法。
OBJECTIVE: In view of the fact that most waterflooding oilfields have entered the period of high water cut and oil recovery at present, the dynamic characteristics of liquid production and water consumption of different types of oilfields are analyzed. Methods: Waterflooding oilfields were divided into different types according to the non-solid production (oil) index. Results: The law of the change of liquid production (oil) index in the development of three different types of oil fields in Liaohe Oilfield was studied. Conclusion: According to the variation law of oil recovery (oil) index in different types of oilfields, adopting corresponding steady oil control measures can provide a simple and practical method for realizing stable or slowdown of oilfield in medium and high water cut periods.
