缓蚀剂在流动条件下的缓蚀性能研究进展

摘要

The corrosion inhibitor is used to inhibit internal corrosion in oil and gas gathering and transferring to extend service life of pipeline and reduce production cost.But under the condition of complex flow,the inhibitor is not as good as being wanted.The mechanism of organic inhibitors and research methods were introduced and the effect of sands,flow velocity,flow regimes and oil phase on inhibition efficiencies and its mechanism were summarized and discussed.The developed trend was also predicted.%为了延长管道寿命、降低生产成本,在油气集输过程中往往会添加缓蚀剂抑制管道的内腐蚀,但流动条件下的缓蚀剂性能并不理想.简要介绍了有机缓蚀剂的作用机理以及研究缓蚀性能的常用方法,对砂、流速、流型、油相等因素对缓蚀性能的影响和作用机理进行了综述和讨论,并对以后的研究方向做了展望.
