摘要
使用尼可尼泵-溶气塔组成的臭氧水制备系统,在溶气塔压力为0.25MPa时,使臭氧溶解效率达到90%以上。该系统用于油田回注水的杀菌处理,在接触时间为30min时,臭氧投加量为8.8g/t,硫酸盐还原菌、铁细菌和腐生菌灭菌率可达到中等渗透油藏注入水A2级指标。
Ozone water preparing system which constituted by Nikeni pump and dissolved gas tower was studied.When dissolved gas pressure stands at 0.25MPa,the ozone dissolved ratio can exceed 90%.The system can be used to treat oil-field injection water,when the oxidation time arrives at 30min,the ozone added should be 8.8g/t,and the sterilization ratio of sulfate reducing bacteria,iron bacteria and saprophytic bacteria can reach A2 level stipulated for injecting water in middle-pervious bed.
