摘　　要：为提高唐80井区的开发速度和提高采收率,同时为整个油田补充能量,开展了唐80井区注空气泡沫提高驱油效率室内试验研究。试验结果表明,小段塞空气-泡沫液交替注入驱油效率最高,且容易注入。从产生的泡沫品质看,气液比在2∶1-4∶1之间,生成的泡沫非常细腻,且在气液比大于5∶1之后容易气窜。经济上考虑,推荐气液比为3∶1。该研究为下一步进行矿场先导性试验提供了一定指导。Experiment research of air foam flooding in Tang 80 well field has been conducted for EOR in the block with incremental producing energy.The result shows that the injection of air pill alternating foam is better than other displacement methods,which is easy to flood;when the gas-liquid ratio is between 2∶ 1-4∶ 1,foam quality is very good;but gas breakthrough appear very soon when the gas-liquid ratio is greater than 5∶ 1.so the gas-liquid ratio with 3∶ 1 is a goog chance based on economic considerations.Field pilot application is worthy studied.
