摘　　要：气顶油藏作为一类较为复杂的油气藏在开发中遇到的最主要问题是气顶气锥进,造成油井气窜,解决这一问题较好的方法是在油气界面处注水形成水障,以隔离气顶和油藏,达到抑制气体锥进,阻止油井气窜的目的。文章以新疆油田分公司莫北2井区气顶油藏为例,对气顶油藏屏障注水技术进行了研究。the main problem encountered during the complex oil/gas reservoir exploration： gas cap reservoir is gas cap fingering, which resulting in the trip gas of oil well. The way to resolve the problem is to form the waterbarrier at the gas-oil interface by water injection in order to isolate the gas cap and the reservoir, restrict the gas fingering, and the trip gas. This paper takes the in the Mobei 2 Well section of Xinjiang oil field as example to conductthe shelter water injection technique study in gas cap reservoir.
