摘要
为了更精确地分析油水井在地下的注采关系,应该确立注水井合理地层压力,确立注水井各层水量劈分系数,以及确定生产井产液量来源于各注水井的方向比例系数。通过研究提出了合理配注预测的方法,并建立了合理配注优化数学模型,为新老注水井之间的水量劈分提出了新的计算方法,为油田调整方案的编制提供了理论依据,最终实现了区块注水井在各层系上的“动态合理配注”。从而最大限度地解决了高含水后期的层间矛盾和平面矛盾,满足了油田稳产和“稳油控水”的需要。
For exactly analyzing the relation of injection-production, the rational formation pressure should be established and the distribution coefficient of all layers of waterflood injection well should be determined and the direction coefficient of fluid output fluid output of producing well rooting in all flooding wells should be given. A reasonable forecast method of match injection was put forward in this paper by series of investigations and the optimization model about reasonable match injection was erected. So a new calculation means was given for water distribution among new and old waterflood injection wells, and a theory gist was offered for weaving the oilfield adjustment project. It realizes dynamic reasonable match in all zone system. It will solve inter-zone and plane conflict mostly to satisfy oilfield stationary production and the requires of firm oil and control water.
