Abstract:

SAGD technology is studied by using numerical simulation and physical simulation methods,the enhancing recovery mechanism of none-condensate gas in SAGD,the application and effectiveness of SAGD in UTF project abroad are traced and analyzed,it is recognized that adding none-condensate gas to steam is an operable method technically.None-condensate gas moves in front of steam,and there is higher oil drainage efficiency,effective expansion of SAGD steam chamber can be maintained,better recovery rate and oil-gas ratio can be obtained,the mount of used steam is saved.UTF in-situ test data and obtained conclusions are helpful for following up SAGD development,the technique is verified to be valuable for wide application and popularization.

Key words: SAGD, steam flooding, none-condensate gas, technology, research
