摘要
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。
The study of drainage rate in the water-injection developing oilfield is an important subject inexploitting the internal potentials of oilfield, increasing the developing effect and the Ultimate recovery factor. Inthe consideration of the fact that at present, most of the water-irijection developing oilfields have entered into theperied of the high-cut-water. This article analyses the drainage rate employed in all kinds of oilfield. Stabilizingthe preduction and controlling the cut-water, which was based on the detailed study of the dimenisionless, recov-ery used in the production period of the three different kinds of oilfields in Liaohe and the vdriation reqularity ofliquid production index. This article intreduces a more practical and simplified method for stabi1izing the preduc-tion and retarding the preduction decline in the high cut-water period.
