注水开发油田提高采液量和稳油控水研究

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。；方法根据无因次采液指数把注水开发油田分成不同类理型。

Increasing Discharge Rate and Controlling Water Cut for Water Flooding Oilfield

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.
