摘　　要：主要讨论了海上石油平台中金属腐蚀的类型、机理、影响因素及防护措施。腐蚀类型包括均匀腐蚀和局部腐蚀(点蚀、缝隙腐蚀、应力腐蚀开裂、腐蚀疲劳),其成因涉及电化学、化学反应以及微生物作用。海水的盐分、湿气、氧气、温度变化和生物侵蚀是腐蚀的主要驱动因素。通过深入分析腐蚀类型和成因,可探索更有效的腐蚀防护策略,以提高平台的安全性和可靠性。This article discusses the types,mechanisms,influencing factors,and protective measures of metal corrosion in offshore oil platforms.The types of corrosion include uniform corrosion and localized corrosion(pitting corrosion,crevice corrosion,stress corrosion cracking,corrosion fatigue),and their causes involve electrochemistry,chemical reactions,and microbial action.The salinity,moisture,oxygen,temperature changes,and biological erosion of seawater are the main driving factors for corrosion.Through in-depth analysis of corrosion types and causes,more effective corrosion protection strategies can be explored to improve the safety and reliability of the platform.
