微生物诱导腐蚀（ＭＩＣ）是油田采出水处理系统腐蚀的主要原因之一。为了减少ＭＩＣ，一般采用投加杀菌剂的方法。二氧化氯是一种广泛用于循环冷却水和饮用水的高效杀菌剂，作者对二氧化氯用于油田采出水杀菌处理的可能性进行了研究探讨。实验证明，在采出水中还原物质含量较低时，二氧化氯对油田采出水有较好的杀菌效果，而且其破胶互沉作用有助于水质净化 Microbial induced corrosion (MIC) is one of the main reasons for the corrosion of oil production water treatment system. In order to reduce the MIC, the general method of adding fungicides. Chlorine dioxide is a highly effective bactericide widely used in circulating cooling water and drinking water. The author has studied the possibility of bactericidal treatment using chlorine dioxide for producing water in oil field. Experiments show that when the recovery of water in the lower content of reducing substances, chlorine dioxide on the oil field produced water has a good bactericidal effect, and its plastic gel subsidence contribute to water purification
