摘　　要：目前,国内油田现有的废水处理工艺和设备已满足不了开发低渗透油田所必需的高水质、大水量和低成本的要求,由于水质差造成了注水系统中普遍存在的腐蚀、结垢和阻塞等问题,严重影响着原油生产.在以回注为目标的采油废水处理中,杀菌对实现水质达标具有重要意义.通过二氧化氯对SRB的灭菌实验,确定了投剂量和接触反应时间,对杀菌机理进行了探讨,为今后油田水处理工艺的技术改造提供了理论依据.The existing technology and equipment of treatment for oily wasterwater can not meet the needs of water injection with high quality, large quantity and low cost, which is needed for exploiting low penetration oil field. Because of low water quality, problems such as corrosion scale and barricale are often seen in the water reinjection system, which gravely influences the production of crude oil. So in the process of oily wasterwater treatment for injection water use, the indisfector to all kinds of bacteria is very important. This paper presents an experiment of the disinfector to SRB by utilizing chlorine dioxide. In test, the optimum operation condition is studied, and the intensity of disinfector, hydraulic resident time is definded. All the outcomes will provide some benefit.
