摘　　要：提出了评价油田水驱开发效果的一个新方法,也就是直接用任一时刻综合含水比与相对应的采出程度之比来评价油田水驱开发效果。其方法简单,所需的资料丰富,实用性强,所计算的参数对于不同类型的油藏具有明显的分辨率,对于同一油藏既有随时间变化的特点,又有良好的一致性,也有明显的变化规律。尤其是在油田开发中后期,其参数趋于稳定,它能真实地评价一个油田水驱开发效果,在油田开发末期,可以评价油田的最终水驱开发效果,实际应用效果良好。This paper presents a new method for evaluation of oilfield development effectiveness by waterflooding,that is directly using the ratio of instantaneous composite water cut vs corresponding recovery percent to do it.This method is simple and plenty of data are available.The estimated parameters are of distinctive resolution for different types of reservoirs;for the same reservoir,the parameters are either characterized by changing with time,or by coher-ence and evident varied patterns.In particular,during mid-late period of oilfield development,these parameters tend to-wards being constant,which provide real evaluation of waterflooding efficiency;in late period of field exploitation,the method can be used for better evaluation of ultimate efficiency of an oilfield by waterflooding process.
