摘　　要：主要针对目前扎那若尔(Zhanarol)油田部分注水井因地层气体沿油、技套环空上窜,并在该环空累计,形成一定的压力,其压力值随气体的积聚不断升高,给注水过程中井口的安全带来一定的威胁。针对该问题,本文提出了具体治理思路及解决方案,采用机械与化学结合的方式将一定高度的油、技套环空彻底封堵,切断气体上窜的通道,以阻止气体在井口积聚而形成压力威胁,该工艺在现场以964井为例进行了试验,已达到预期效果。This article mainly aims at the partial water-injection wells of Zhanarol oil field at present because of the stratum gas along the annulus space of oil string and intermediate string,and forms certain pressure in the annulus space,which accumulates continually,and brings certain threat to the well head.In view of this problem,this article proposed the train of researching thoughts and the solution,we used the combination way of machinery and the chemical to plug certain height of annulus space of oil string and intermediate string fully,and prevent the gas accumulate in the well head.this technics has experimentized on the 964 well,and has achieved the expected effect.
