摘　　要：含水采出比是评价注水油田开发效果的一个新参数。基于甲型和丙型水驱特征曲线,分别建立了含水采出比的理论关系式,以及用于特定油藏开发效果评价的含水采出比理论曲线,揭示了不同水驱特征规律下油田含水采出比的变化特征。通过实例,对建立的理论方法进行了应用评价。结果表明,含水采出比的理论符合油田的实际情况,该方法用于注水油田开发效果的评价,简便可行。Water cut-recovery percent ratio is a new parameter tbr evaluating development efficiency of water flooding reservoirs. Based on Type-A and Type-C water flooding curves, the theoretical expressions for water cut-recovery percent ratio and their theoretical curves are established, respectively, and the changing feature under different water flooding laws are revealed. The case application resuhs show that the theory corresponds to field situation, and the methods can be used to evaluate development efficiency of water flooding reservoirs.
