摘要
针对稠油在注蒸汽开采中发生的汽窜问题，阐述了蒸汽泡沫调剖的应用机理，在室内对各种泡沫剂进行了性能评价，并对调剖敏感因素的影响及泡沫注入方式的筛选进行了研究，同时通过现场应用效果分析，证实了蒸汽泡沫调创对提高采收率具有显著效果．
in accordance with steam scurrying problem arosed during recovery of heavyoil by steam injection, this paper discusses the application mechanism of steam-foam profilecontrol, evaluates the indoor performance of various foam agent, and also studys the influences of sensible factors of profile controle and the selection of foam injection mode.Through analysis of field application result, it is verified that steam--foam profile control isquite helpful for enhancing recovery factor.
