摘　　要：本文分析了稠油油藏蒸汽驱汽窜情况及其成因 ,研究了一些防汽窜的措施 ,提出了在蒸汽驱阶段利用循环转注方式生产有望延缓汽窜的发生并提高蒸汽总体波及体积和最终采收率。This paper studies steam channeling in steam flooding of heavy oil reservoir and its cause of formation,discusses some practice of anti-channeling and puts forward the rotator convert injecting direction and increasing more wells between production and injection wells to slow the steam channeling development and enhance the breakthrough volume and ultimately recovery ratio.

关 键 词：稠油油藏 蒸汽驱 汽窜 循环转注 波及体积 采收率
