摘　　要：存水率标准曲线是油藏在不同注采比开发情况下的一组存水率随采出程度的增加而变化的理论曲线,可利用其与实际曲线的对比进行注水开发效果的评价;目前利用油藏实际水驱曲线延伸趋势推导建立存水率标准曲线的方法应用较广,但是其中隐含了一个与油藏开发规律相矛盾的逻辑漏洞,致使该方法建立的标准曲线不标准。Reservoir water storage rate standard curve is the theoretical curve that varies with the degree of recovery in different injection-production ratio cases,compared with the actual curve to evaluate the effect of water flooding.This widely used method establishes water storage rate standard curve using extension of trend in the real reservoir water drive curve derived; but there is a logic vulnerability which conflicts with the laws of reservoir development, and the standard curve is not standard as a result.

关 键 词：存水率 标准曲线
