摘　　要：针对以往常采用剩余油饱和度单一指标来评价剩余油潜力,只能反映、评价某一部位水淹程度,而不能量化潜力大小的缺点,为适应注水开发油田特高含水开发期的要求,本文通过计算剩余储量丰度经济界限,从而运用含油饱和度-剩余储量丰度联立评价,将剩余油潜力分为三大类六亚类,并提出相应的挖潜对策。Evaluation of residual oil potential with residual oil saturation as the only index can only estimate the watered-out degree in a certain area but cannot give out quantita-tive evaluation results.In view of the specific situations of development at ultra-high water-cut stage in waterflooding oilfields,residual oil potential are divided into3types and6subtypes through calculating economic limits of residual reserves and simultaneously evaluating the abundance of oil saturation and residual reserves.Corresponding potential tapping measures are presented in this paper.
