| 摘 要： | 借助室内实验和数值模拟,研究了氮气泡沫热水驱提高稠油采收率的机理.结果表明:在注热水的同时注入氮气和泡沫可以大大提高稠油的采收率,其机理主要表现在降黏、原油体积膨胀、调剖等方面.氮气泡沫热水驱和热水驱的对比试验显示氮气泡沫热水驱不仅可以提高采收率,而且还可以提高采油速度.

| Abstract: | the mechanism of nitrogen hot water foam flooding is studied by laboratory experiments and numerical simulation. The results show that at the same time as hot water is injected, injecting nitrogen and foam can greatly enhance the recovery factor of heavy oil. The increase of recovery factor is mainly due to viscosity reduction and volume expansion of heavy oil, profile control effect of foam, etc. The comparing experiments of nitrogen hot water foam flooding with hot water flooding show that nitrogen hot water foam flooding can not only enhance recovery factor, but also increase rate of oil production. |
