摘要
控水稳油是注水开发油田改善高含水期开发效果的必然要求。该文在研究水井动态控制图绘制原理及其在控水稳油中的应用上作了有益的探索，并取得了明显的效果。应用水井动态控制图就是从注采比和注水压力两方面着手，对注水井当前注水的合理性进行图版验证，进而为控水稳油措施的提出指明方向，它为控水稳油工作的开展提供了一条快捷方便的途径，这在胜利油田尚属首次，具有广阔的推广应用前景。
Stabilizing oil production by water control is requisite to improve development efficiency in high water cut period of waterflooded oil field.This paper discusses the principles for drawing water well performance control plot and its application in stabilizing oil production by water control.Through the application of water well performance control plot,the reasonableness of current water injection status of water injector is testified by using plot in terms of injection-production ratio and injection pressure.Thus the measures of stabilizing oil production by water control is brought about,providing a rapid and easy way for implementing the work of stablizing oil production.This method is used in Shengli oil field,and has wide popularizing and application prospects.
