摘　　要：运用相对渗透率曲线计算了纵向砂体的剩余油饱和度分布,结果表明,当油田综合含水率为98%时,水驱剩余油饱和度为40.13%,可动油饱和度为13.41%,油层存在非均质性,在剩余油饱和度相对高的部位仍有一定潜力;濮南沙二上2+3油藏平均油水相对渗透率曲线具有较好的代表性,可以在特高含水油藏中应用。This paper has calculated the remaining oil saturation of the portrait sand body by the relarive permeability curve, and described that the remaining oil saturation was gotten 40. 13%, and the mobile oil saturation was gotten 13.41% when the was 98%. At the same time it has showed the heterogeneous reservoir has the development future at the high remaining oil saturation area. So the average oil and water relative permeability curve has well representative in the Upper ES^243 oil Reservoir, south of Pucheng oil field. And this method also has the significance to other similar high water cut reservoir.
