摘要
不锈钢因其具有优良的耐蚀性被大量应用于油气田环境中。但是,在复杂的油气田环境中不锈钢仍旧会发生点蚀。为了保证不锈钢能够安全服役,从不锈钢材料的点蚀机制、点蚀影响因素等方面综述了不锈钢在油气田环境中的点蚀研究现状,并针对其研究的不足对其研究方向进行了展望。
Stainless steel is widely used in oil and gas field environment due to its excellent corrosion resistance.However,in some complex oil and gas fields,stainless steel is still prone to pitting corrosion.In order to ensure the safe service of stainless steel,the status of pitting corrosion of stainless steel in oil and gas field environment is reviewed from the respects of pitting mechanism and influence factors of pitting corrosion.And the research directions are proposed according to the research shortages about pitting corrosion of stainless steel in oil and gas field environment.
