摘　　要：油藏进行注水开发后 ,建立合理的注采平衡系统 ,不仅可以充分发挥油水井的生产能力 ,节约能耗 ,同时为获得最大产液量创造条件。为了搞清在高含水采油阶段 ,油藏产液能力、吸水能力、含水上升等变化规律 ,可以结合各方面因素 ,如地层压力、流压、注水压力、采液(油 )指数及油水井数的变化等 ,从油藏实际出发 ,在分析研究的基础上 ,利用注采平衡交汇图 。To make good use of well productivity, save cost and get maximal production fluid, it is necessary to build rational injected and produced voidage balance in water-flooding reservoir in the high watercut stage of the oil filed. To know the variation law such as producing capacity, injecting, watercut increasing and so on, we can study the injected and produced voidage balance system by its crossplot on the base of analysis and study of layer pressure, injection pressure, productivity, producing index and the amount of wells.
