摘　　要：岩心是认识油藏最直接的实物资料,特别是水淹严重的注水开发油藏,剩余油分布复杂,应用密闭取心资料开展储层构型和油滴尺度下的剩余油研究,可为高含水阶段油藏下步开发提供科学依据。本文以沧东凹陷3口密闭取心井资料为基础进行了剩余油研究,总结了密闭取心井储层构型和油滴尺度下的剩余油研究方法,开展了储层构型和油滴尺度下的剩余油研究,总结了剩余油分布规律,并进行现场应用,取得较好效果。Core is the most direct data to understand the reservoir,especially for seriously waterflooded reservoir with complex distribution of remaining oil.The study of remaining oil in reservoir architecture and oil-drop scale which applied with sealed coring data can provide scientific basis for reservoir development in high water cut stage.Based on the data of three sealed coring wells in Cangdong depression,the remaining-oil research methods at the scale of reservoir architecture and oil drop are summarized,the research of remaining oil at the scale of reservoir architecture and oil drop is carried out,and the distribution of remaining oil is summarized which are applied in the field and achieve good results.
