摘　　要：在模拟油藏条件下进行了CO_2泡沫驱、N_2泡沫驱和天然气泡沫驱3种不同气体泡沫驱的室内模拟实验研究,以确定合适的不同气体类型及其对泡沫驱效果的影响。实验结果表明:最佳复合的起泡剂浓度为:0.5%AOS+0.2%ABS,在该油藏条件下,CO_2泡沫驱阻力因子大于N_2、天然气泡沫驱,封堵能力更强。CO_2泡沫调驱提高采收率17.8%左右,明显好于N_2、天然气泡沫驱,适合用于吉林油田木146区块泡沫调驱技术。After decades of water flooding development, the target block has already entered the three high phase of high fluid production, high water-cut and high recovery percentage, and the water flooding effect is poor. In order to improve reservoir development effect, choose reasonable development way, under the simulated reservoir conditions, the different gases CO2 foam flooding, N2 foam flooding and natural gas foam flooding indoor simulation experiment were been tested, to determine the appropriate type of different gases and its impact on foam flooding effect. Also in order to choose the best gas for Mu 146 block. Experiment results show that the best concentration of foam agent is 0.5% AOS＋0.2%ABS. Under the condition of the reservoir, the foam resistance factor of CO2 is bigger than N2 and natural gas, the sealing ability of CO2 is stronger. Foam flooding to improve oil recovery of CO2 is about 17.8%, much better than N2 foam flooding and natural gas flooding. What is more that there has the rich CO2 gas source around Mu 146 block （Changling gas field）, so choosing the CO2 gas for foam flooding technology is more suitable in Mu146 block.
