二氧化氯杀菌剂在油田回注水处理中的应用

Application of Chlorine Dioxide in Treating Oilfield Circulated Injected Water

在油田回注污水的杀菌处理中,常规非氧化剂型杀菌剂存在作用缓慢、易使细菌产生抗药性的弊端,而二氧化氯是强氧化剂,作为杀菌剂使用有广谱、高效且不会使细菌产生抗药性的优点,在油田回注水的杀菌处理中得到了越来越广泛的应用。

In the disinfection of oilfield circulated injected water, normal nonoxidative bactericide is slowly effective and bound to cause bacteria＇s drug resistance. But chlorine dioxide, a kind of strong oxidative agent, is broad-spectrum and of high efficiency. What＇s more, it can not cause bacteria＇s drug resistance. So it is more and more widely used in the disinfection of oilfield circulated injected water.
