摘　　要：注水井合理配注是油田注水开发管理工作的一项重要内容,以提高油田注水开发效果为目标,研究了注水井注水量的定量化配置问题。根据注水开发油田特有的水驱特征曲线关系式,推导出了两种利用配产量确定区块配注量的计算模型,并建立了符合油田实际情况的注水井注水量劈分系数。应用表明,该计算模型具有一定精度、实践性较强,为注水井合理调配提供了依据。Reasonable injection of water injection well is an important part of water injection development and managementin oil field. In order to improve the effect of water injection development in oil field, the problem of quantitative allocation of waterinjection in water injection wells is studied. According to the unique development of oilfield water flooding characteristic curveequation, deduced two kinds of model of calculating block injection volume by using with yield, and the use of injection quantityis established in accordance with the actual situation of oil field splitting coefficient, the application shows that the model has certainprecision, strong practicality, provides the basis for for a reasonable allocation of water injection wells.
