摘　　要：间歇汽驱是吞吐开发后期提高浅薄层稠油采收率的一种行之有效的方法。结合泌浅 10区Ⅳ9层浅薄特超稠油油藏特点 ,分析了间歇汽驱现场试验效果和生产特点 ,结果表明 3个井组间歇汽驱试验油汽比达到 0 2 5。通过试验对吞吐后油藏油水分布有了新的认识 ,间歇汽驱成功关键在于汽驱井组优选。Interval steam injection is an effective method for enhancing thin layer viscous oil recovery of late oil development of steam injection. In combination with the characteristics of shallow thin layer ultra-viscous oil in Zone IV9 of Biqian Region 10, the effect of field test and production features of the interval steam injection are analyzed. The results show that steam-oil ratio of the interval steam injection test is 0.25 in 3 well groups. New understanding of reservoir oil and water distribution of the cyclic steam injection is obtained through experiments. The key of the interval steam injection success is optimal selection of steam injection well group, the techniques of profile control and channeling plugging in steam injection wells and optimized arrangement of injection-production parameters.
