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.
