摘　　要：目前赵凹油田安棚区核桃园组三段4亚段2层(Eh4(2)3)进入特高含水期,剩余油在空间分布上十分复杂,挖潜难度大。从储量丰度、水淹级别统计剩余油的分布规律,确定各小层剩余油的形成因素和对应的剩余储量;同时对小层叠合后的剩余油富集区进行定量评价,确定剩余油潜力区,为油田下一步对剩余油的开发提供了依据。The Eh4(2)3of Hetaoyuan Formation in Anpentg Area of Zhao'ao Oilfield was at extra-high water-cut stage,the special distribution of residual oil was complicated,and it was hard for tapping the potential of residual oil.Based on the reserves abundance,and level of water-out,The statistical analysis was made on the distribution law of residuals oil from reserves abundance to waterflooding grades,the factors of forming the residual oil and corresponding to different control factors in each sublayer were determined.Quantitative evaluation is made on remaining oil enriched areas and potential areas of remaining oil is determined,it provides basis for next development of residual oil in the oilfield.
