摘　　要：注水开发油田在长期注水之后，不可避免地产生一部分无效注水，本文运用理论推导和实际资料相结合的方法，引入了“有效注采比”的概念，通过对一个油田（或单元）无效注水比例的测算，确定出在不同压力保持水平、不同采液速度下的注采比及在合理压力保持水平、合理采液速度下的合理注采比，为油田进行合理的配产配注提供理论依据。There exist inevitably some inefficient injection water after a long period of water injection in waterflooding oilfield. A concept of' effective production factor' is introduced in this paper through combining theoretical derivation with real data. Production factors at different pressure maintenance levels and fluid production rates and rational production factor at rational pressure maintenance level and fluid production rate can be determined through calculating the ratio of inefficient injection water in an oilfield unit. They provide theoretical basis for rational production proration and injection allocation in an oilfie1d.
