摘　　要：活跃边底水稠油油藏高轮次吞吐以后 ,由于受储层非均质性、开采方式、油藏边底水、射孔井段等因素影响 ,剩余油分布规律复杂 ,蒸汽吞吐开采效果变差。通过对活跃边底水稠油油藏高轮次吞吐阶段剩余油分布规律和影响因素的研究 ,利用新钻井、定向侧钻、扶停产井完善井网 ,采用补孔扩射调整注汽产液剖面、注氮气或注氮气加化学剂控制水锥等手段 ,改善了高轮次吞吐稠油油藏开发效果 ,在单家寺稠油油藏应用后取得了较好的成效。After the high order turnover of active bottom thicked oil,the distribution regularity of residual oil became complicated and the exploitation effect became worse due to influence of reservior inhomogeneity,exploitation method and bottom water.In this paper,the distribution regularity of residual oil during the stage of high order turnover of thickened oil was discussed.The research showed that the use of new drilling,oriented drilling and nitrogen injection together with the addition of chemical reagent could improve the exploitation effect of oil pool.The practical application of the method to the Shanjiasi thickened oil pool achieved satisfactory result.
