| 摘 要： | 为了改善秦皇岛32—6油田的水驱开发效果，开展了氮气泡沫调驱提高稠油呆收率室内实验研究。通过泡沫剂的静态性能和动态性能评价，筛选出泡沫剂及其配方。在此基础上，研究了氮气泡沫的驱油特点。研究结果表明，在气液比为1：2时，氮气泡沫的阻力因子大于160，泡沫剂的最佳质量分数为0．3％～0．5％。氮气泡沫调驱能够较好地改善水驱效果，在水驱的基础上提高原油采收率达26％。 |

| Abstract: | Nitrogen foam flooding for enhancing oil recovery was studied by laboratory experiment to improve water flooding efficiency in Qinhuangdao 32-6 Oilfield with heavy oil.Foam agent and for- mulation were selected after the static and dynamic performance was evaluated.Then nitrogen foam flooding was researched by observing its character in cores.The resistance factor of nitrogen foam was bigger than 160 and the best foam agent concentration was between 0.3% and 0.5% when the ratio of gas-to-liquid was 1:2.Nitr... |
| Keywords: | nitrogen foam flooding foam agent offshore heavy oil reservoir Qinhuangdao 32-6 Oilfield |
