摘　　要：存水率是描述油田注水能量利用率及评价油田注水开发效果的重要指标之一,但传统存水率的概念具有一定的局限性,使其不能得到广泛应用。基于存水率的物理意义,提出了广义存水率的定义,应用广义存水率可以反映具有边、底水油田的注水开发效果,并考虑到了油田弹性能量的作用。实例表明,广义阶段存水率下降的速度体现了油田的开发效果;在不同的油田含水阶段,广义累积存水率与含水率之间呈不同的线性关系。Water storage is one of important parameters to describe the utilization factor of water injection energy and evaluate the effectiveness of water flooding reservoir. However, the traditional water storage could not be widely used for its limitation of concept. This paper proposed the definition of generalized water storage, which could reflect the effectiveness of water flooding reservoir with edge or bottom water and take the elastic energy into consideration. The case study showed that the effectiveness of water flooding reservoir can be embodied by the speed of generalized phase water storage decline; there exists different linear correlation between the generalized cumulative water storage and the water cut.
