摘　　要：油田采出液中Cl^(-)含量越来越高,导致注采系统、集输系统用材料的腐蚀愈来愈严重。对石油管材在含氯离子介质中的腐蚀行为研究现状进行了综述,总结了其腐蚀机理、影响因素和腐蚀特征。介绍了Cl^(-)与HCO_(3)^(-)、Ca^(2+)以及CO_(2)-O_(2)-Cl^(-)协同作用下对石油管材腐蚀的影响规律,指出当前研究的不足之处,为后期研究方向以及预防措施的选择提供参考。Higher and higher Cl^(-)content in oilfield produced fluid leads to more and more serious corrosion of materials used in injection and production system and gathering and transportation system.This paper reviews the research status on corrosion behavior of petroleum tubular goods in chloride containing medium,and summarizes the corrosion mechanism,influencing factors and corrosion characteristics.In addition,it introduces the synergetic corrosion behavior of petroleum tubular goods with existence of Cl^(-),HCO_(3)^(-),Ca^(2+) as well as CO_(2),O_(2),and Cl^(-),and points out the inadequacies of current research,which provides reference for the future research direction and the selection of preventive measures.
