为进一步提高油田污水处理及回注技术,笔者结合出国考察情况,提出应根据各油田的特点,制定不同的水质标准,特别应严格控制注入水中溶解氧的含量。笔者着重介绍了对注水水质的要求;氧的腐蚀机理;油田污水处理和注水系统的密闭隔氧和除氧的意义及措施。
In order to further improve the technology of wastewater treatment and reinjection in oilfields, the author proposes that different water quality standards should be formulated according to the characteristics of each oilfield. In particular, the dissolved oxygen content in water injected should be strictly controlled. The author focuses on the water quality requirements of the injection; corrosion mechanism of oxygen; oil field sewage treatment and water injection system of oxygen and oxygen sealing significance and measures.
