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 ,进行注采平衡系统研究 After the reservoir is developed for waterflooding, the establishment of a reasonable injection and production balance system can not only give full play to the production capacity of oil and water wells, save energy and create the conditions for obtaining the maximum production volume. In order to find out the variation law of fluid production ability, water absorption capacity and water-cut in the reservoir, the factors such as formation pressure, flow pressure, water injection pressure, oil production (oil) index and number of oil and water wells Based on the analysis and research, based on the reservoir actual conditions, the injection-production balance chart is used to study the balance between injection and production
