摘　　要：水驱特征曲线是注水开发油田用来预测动态储量及可采储量等参数的实用方法之一,目前,国内、外学者已经推导出五十多种水驱特征曲线表达式,但每种水驱特征曲线都难以描述油田开发的全过程,都有各自的适用条件。这里通过对甲型水驱曲线和乙型水驱曲线的适用条件、诊断的探讨和分析,认为水驱特征曲线在油田低含水开发阶段和特高含水开发阶段都不适用,它只适用于油田开发的中～高含水阶段。同时在利用水驱特征曲线预测可采储量时,水驱曲线直线段的选取应当慎重,应将甲型水驱曲线与乙型水驱曲线相结合使用,这对于单井来说尤其重要,只有这样才能更好地选取水驱曲线最佳直线段,从而使预测结果更加准确有效。Water drive characteristic curve is one of practical methods that used to predict the oil field water injection dynamic reserves, recoverable reserves and other parameters. At present, Domestic and foreign scholars have deduced 50 kinds of water drive characteristic curve expression, but each water drive characteristic curve is difficult to describe the whole process of oil field development, and has its own application conditions. This article is based on the A and B water drive curve of the applicable conditions, diagnosis, discussion and analysis, and we think that the water drive curve is not suitable in the oil field low watery and especially high watery phase of exploitation, which is only suitable for the oil-field development high watery stage, simultaneously when using water drive curve to predict recoverable resources, the selection of water drive curve line segments must be prudent. It is better unify the Type A water drive curve and the Type B water drive curve to use, especially important for the single well, and only in this way we can select the best water drive curve line segments better, so that the predictions more accurate and effective.
