注水中的溶解氧不仅腐蚀管道和注水设备,而且会对油田开发造成不利影响,为此原石油部专门制定了相关规范,对目前使用的各类除氧方式在油田注水中的适应性进行分析。针对油田注水除氧主要采用的脱氧塔所存在的体积大、效率低、能耗高等缺点,提出了应用真空旋流水除氧装置取代现有设备,详细论述该项新技术的主要工作原理,并分析了其在油田注水除氧工艺应用中的优势。

The dissolution oxygen in injection water not only erode pipeline and water injection equipment, but also affect oilfield development effect, so a correlation criterion was made by CNPC. Every kind of deoxidize fashion in field water flooding were analyzed. The disadvantages of each fashion were pointed out. It was put forward to use vacuum separator with cyclone water deoxidation instead of existence equipment. The main work principium of this new technology was discussed in detail, and the advantages of it using in field water injection were analyzed.
