摘　　要：提出了评价油田水驱开发效果的2个新参数——含水采出比与含水可采比,即直接用任一时刻综合含水率与相对应的采出程度或可采程度之比来评价油田水驱开发效果。该方法所计算的参数可以真实地评价不同类型的油藏以及同一油藏不同时间的水驱开发效果(尤其是在油田开发中后期)。用这2个参数评价油田水驱开发效果,既能反映油田储集层与流体的固有特性,又能反映开发技术与开发政策水平。The instantaneous water cut-recovery percent ratio and water cut-recoverable percent ratio are proposed. The new parameters refer to the ratio of anytime composite water cut to corresponding recovery percent or recoverable percent, which can be used to evaluate efficiency of oilfield development by water flooding process, sutable for different types of reservoirs or different stages of the same reservoir. In particular, during mid-late period of oilfield development, such parameters tend to being constant, providing comprehensive and real evaluation of ultimate water flooding efficiency. Also, using these parameters can not only reflect inherent characteristic of reservoir rock and fluid in an oilfield, but also the levels of development technology and policy.
