| 摘 要： | 介绍了X65耐腐蚀钢材在油田海管中的应用，研究了海管材料X65在多相流及冲刷腐蚀环境下的腐蚀规律，并提出了腐蚀控制措施及建议。试验表明：当流速达到或越过2m／s时．管线的腐蚀加剧；水含量增加时，腐蚀速率也增长，当水质量分数由30％增加到60％时，腐蚀速率由4．07mm/a增大到了14．70mm／a。

| Abstract: | The application of corrosion-resisting X65 steel material for marine pipelines was introduced. The corrosion law of X65 marine pipelines in multi-phase flow and eorrosive environment was studied, and corrosion control measures were recommended. The test showed that the corrosion of pipelines became increasingly serious at a flow velocity of 2 m/s or higher; The corrosion rate increased with increasing water percentage. When the water percentage （m） was increased to 69% from 30%, the corrosion rate was elevated to 14.7 mm/a from 4.07 mm/a. |
