摘要:

利用数值模拟和物理模拟方法对蒸汽辅助重力泻油(SAGD)技术进行研究,对比分析了非凝析气在SAGD中的增产机理,跟踪分析国外UTF项目中SAGP应用情况和效果,认为向蒸汽中添加非凝析气体是一项技术上可行的方法,非凝析气体在蒸汽的前面运动,具有较高的驱油效率,能够维持成熟SAGD蒸汽腔的有效扩展,可以取得较好的产油速度和油汽比,节约了蒸汽的用量;UTF现场试验数据和所得的结论对SAGD的后续开发具有重要的借鉴作用,证明了该工艺具有广泛的推广应用价值。

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
