一、前言金属在自然环境中会发生腐蚀,这是自然界的一种自发过程。钢在含CO_2的盐水中也不例外,天然气开采业中的此类腐蚀问题尤为突出,也是长期来没有得到很好解决的难题。腐蚀科技工作者的任务在于用最少的经费去控制这些腐蚀破坏,延长金属及其设备的使用寿命,确保生产安全运行。往腐蚀性系统中添加缓蚀剂改变介质组分以抑制或降低金属腐蚀作用是与腐蚀作斗争的途径之一。这种方法已被人们广泛研究和应用,公认为是一种成功的防腐途径。
I. Introduction Metal corrosion occurs in the natural environment, which is a spontaneous process in nature. Steel is also an exception in CO 2 -containing brines, and such corrosion problems are particularly acute in the natural gas extraction industry, which is also a difficult problem that has not been well addressed in the long term. Corrosion The job of a technologist is to control these corrosion damage with the least amount of expense, extend the service life of the metal and its equipment, and ensure the safe operation of the production. Adding Corrosion Inhibitors to Corrosive Systems Changing media components to suppress or reduce metal corrosion is one of the ways to combat corrosion. This method has been extensively researched and applied by people and is generally regarded as a successful anticorrosion route.
