油田杀菌工艺及杀菌剂研究进展

Research progress of sterilization process and bactericides used in oilfield

在油田开采、集输和注水系统中,细菌对管线及其设备造成了严重的生物腐蚀,给油气生产带来了巨大的损失,因此适宜的杀菌工艺方法与高效杀菌剂在油田的应用显得尤为重要。文中总结了油田注水系统常用的杀菌工艺及杀菌剂的研究应用现状,分析了各自的杀菌机理及其特点,最后展望了油田注水系统杀菌工艺及杀菌剂的发展趋势。

The bacteria had brought serious biological corrosion to the pipelines and equipment of oil and gas gathering and transferring system and the flooding system in oil production, and lead enormous losing to the oilfield, so reasonable application of sterilization process and bactericides were very important to the oilfield. The research and application actuality of sterilization process and bactericides in flooding system of domestic oilfield were discussed in this paper, further more, the sterilization mechanisms and relative merits of different sterilization process and bactericides were introduced and compared, and their future study and development were expected.
