摘要： 根据双膜理论的基本理论关系式,推导了海上平台过滤器反冲洗时反冲洗曝气对生产水注水流程含氧量影响的理论计算式。以此计算式为基础,分析了不同反冲洗方式对流程含氧量的影响,试算了某海上油田注水流程反冲洗系统对流程含氧量的影响。分析结果表明,在目前海上生产的实际情况下,先气后水的反冲洗方式不足以使生产水注水系统含氧量的增加超出规范所限定的范围。

Abstract: According to the basic theoretical formula of two-film theory, we derive the calculation formula of oxygen content change in the offshore platform water injection system after air-water backwash. On the basis of the calculation formula, the effects of different backwash methods on the oxygen content in the process are analyzed, and the influence of the water injection process in a certain offshore oilfield on the oxygen content of the process is analyzed. Analysis results show that the air-water alternative backwash mode in offshore platform will not lead the oxygen content change to exceed the limit for injection water defined in related standards.
