| 摘 要： | 利用油藏数值模拟、剩余油饱和度监测、钻密闭取心井、常规油藏工程分析等手段，寻找单家寺油田单10块稠油热采油藏剩余油饱和度的相对富集区。通过新钻井、老井侧钻、深度调剖、注氮气等技术进行剩余油挖潜，油藏开发效果得到明显改善。综合递减率下降10．0％，采收率提高2．94％，油汽比上升0．11。对单10块剩余油研究拓展了多轮次吞吐稠油油藏的挖潜方向，对同类油藏改善开发效果和提高采收率具有参考价值。

| Abstract: | Relative enrichment area of remaining oil saturation in heavy oil reservoir by thermal recovery of Shan 10 block in Shanjiasi oilfield is looked for using the measures of reservoir numerical simulation, remaining oil saturation monitoring, drilling pressure cored well , normal reservoir engineering analysis. Reservoir development effect is improved obviously by tapping the potential of the remaining oil with the technologies of drilling new well, sidetrack drilling of old wells, deep profile control, nitrogen injection. Composite decline rate decreased 10. 0% , recovery efficiency enhanced 2.94% and oil-steam ratio raised 0. 11. The research of the remaining oil in Shan 10 block enriched the direction in tapping potential of multicyclic steam stimulation in heavy oil reservoir, and has reference value for improving the development results and enhancing recovery efficiency in the same type of the oil reservoir. |
