摘　　要：针对高含水油藏地下油水关系复杂、剩余油分布零散的难点,以双河油田北块Ⅳ5-11层系为例,通过油藏数值模拟手段,综合剩余储量大小、储层物性、渗流规律、目前注采井网完善程度、注采对应状况和开采情况等条件,求出优势潜力指标,确定出剩余油优势开发潜力区域。结果表明,当研究区Ⅳ5-11层系剩余油潜力值大于0.38时,所对应的剩余油饱和度和剩余储量丰度都较高;剩余油饱和度在0.4以上,剩余储量丰度则大于0.60×106t/km2。"优势潜力指标"法评价剩余油潜力,不仅可以了解地下剩余油的具体分布情况,还能够获知不同区域剩余量的大小,是一种有效的剩余油潜力预测新方法、新思路,对同类油田的开发调整具有重要的指导意义。In allusion to the problems of complex relation between oil and fragmented remaining oil distribution in the reservoirs with high water cut,by taking Ⅳ 5-11 Strata of North Block in Shuanghe Oilfield for example,through the oil reservoir numerical simulation,the advanced potential indexes were obtained according to the size of remaining reserves,reservoir properties,percolation laws,the perfection degree of the current injection patterns and the corresponding injection conditions,the main remaining oil distribution regions were determined.The results show that the corresponding remaining oil saturation and remaining abundance are relatively high when the advanced potential indexes are greater than 0.38 in the research area,when the remaining oil saturation is greater than 0.4,its abundance is greater than 0.60×10~6t/km^2.The method of advanced potential indexes can not only be used to describe the distribution,but also the amount of remaining oil,it provides a new idea for effective predicting the remaining oil potential.
