摘　　要：齐40块莲Ⅱ油层于1998年10月和2003年7月先后开展11个井组的蒸汽驱先导试验和扩大试验,目前处于蒸汽驱开发末期的剥蚀阶段。为了最大限度提高蒸汽驱经济效益,运用数值模拟对试验区蒸汽驱后期进行了间歇注汽的研究,设计了间歇方式、间歇时间、注汽速度等参数,现场应用后已见到明显效果,油汽比由0.14上升到0.20。为蒸汽驱后期合理的调整模式提供了借鉴。Qi40 Lin Ⅱ reservoir in October 1998 and July 2003 carried out one after another group of 11 wells of the steam flooding and expansion of pilot testing,is currently in the development of steam flooding late stage of erosion.Steam flooding to maximize economic efficiency,the use of numerical simulation of the experimental area late steamflooding intermittent steam injection of the research,design the intermittent mode,intermittent time parameters such as steam injection speed,on-site applications have to see tangible results,oil than steam rose to 0.20 from 0.14.Steam flooding for the late model provides a reasonable adjustment of the draw.
