【摘要】 油田回注水中的硫酸盐还原菌、腐生菌和铁细菌会造成严重的腐蚀和堵塞问题。本研究对不同条件下二氧化氯杀灭这三类细菌的效果进行了考察,结果表明,应用二氧化氯对油田回注水杀菌是非常合适的。当投量为3.0mg/L时即可满足国家标准,当投量增加至5mg/L时,杀灭率可达100%。延长反应时间可以提高杀菌率。仅反应10min即可使出水达标。温度和pH对杀灭率影响不大。60℃为和pH7～9范围内杀菌效果最好。本研究的结果对二氧化氯在油田杀菌领域的应用提供了必要参数,具有重要的应用价值。更多还原

【Abstract】 Corrosion and plugging caused by sulfate reducting bacteria, total growth bacteria and iron bacteria in the reinjection water is very severe. The sterilization efficiencies of chlorine dioxide on the three kinds of bacteria above were studied in varies conditions. The results prove that ClO2 is suitable to apply in the oil rejection water sterilizing. When the dosage was 3.0 mg/L, the bacteria remains can meet the standards, then raise the dosage up to 5.0mg/L, the sterilization can reach or very close to 100%. Higher sterilization rates can be obtained at longer reaction time. The residue of bacterial can reach the standards just at 10 min. The influence of temperature and pH value was slightly, the best sterilization rate can be gotten at 60oC, and reach to 90% when the pH is within 7~9. Necessary index is provided in the study , which is of great application value.更多还原
