Abstract

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
