摘　　要：采用XRD、XRF、微生物实验和腐蚀模拟实验等方法,结合实际工况,对某平台的注水海管腐蚀原因进行探究,确定海管内腐蚀是输送介质中的溶解氧、管内结垢和细菌腐蚀共同作用引起。针对海管腐蚀现状,提出相应的注水海管腐蚀控制方案与措施。The corrosion causes of water injection sub-sea pipe on a platform were explored by XRD、XRF、bacterial experiment and corrosion simulation experiment,combined with the operation conditions.It was determined that corrosion of the pipeline is caused by dissolved oxygen in the medium,scaling in the pipe and bacterial corrosion.According to the current situation of corrosion,the corresponding corrosion control schemes and measures are put forward.
