摘　　要：针对中原油田回注水中细菌易产生抗药性 ,难以控制的问题 ,提出了应用二氧化氯处理油田回注水工艺。经室内评价及现场试验 ,二氧化氯可杀死回注水中的细菌 ,控制微生物生长 ,同时该工艺可降低现有回注水污泥残渣产出量的 50 % ,减少污泥对环境的污染 。The method of using chlorine dioxide for oilfield back injection water treatment was presented to deal with the drug resistance of bacteria in the water. Laboratory evaluation and field tests showed that chlorine dioxide can be used to kill bacteria in the back injection water, control the growth of microorganisms, and reduce the sludge and residual produce by 50%, thus minimizes the environmental pollution and improves water quality.
