摘　　要：提出了应用威布尔（Ｗｅｉｂｕｌ）增长曲线和一种新型增长曲线ＮＰ＝ＮＲ（ｂｔ－１）／（ｂｔ＋ａ）评价油田调整效果的方法。评价的指标是调整前后油田最终可采储量ＮＲ的变化。提出了实际油田有重大调整措施时的ｔＱｔ－ＮＰ或Ｑｔ－ＮＰ变化的６种模式，及用它们评价调整效果时，增长曲线的适用条件。垦西油田的算例表明，所提的评价方法是合理的和可以实现的。A method for evaluating effect of oilfield adjustment by using Weibull increase curve and a new kind of increase curve, N P=N R max ( b t-1)/(b t +a ), has been proposed. The evaluating index is the change of ultimate recoverable reserves N R max before and after oilfield adjustment. Six kinds of models of tQ t vs N P and Q t vs N P for having important adjustment of oilfield and their applicable conditions at evaluating effect of oilfield adjustment have been proposed. An example of Kenxi oilfield shows that this method is reasonable and can be accomplished.
