摘　　要：南海东部某油田群作业区某平台下岸段海管于2023年应用电磁超声壁厚监检测技术对其壁厚进行实时监检测,首先根据流动加速腐蚀及冲刷腐蚀的模拟数据选取该段管腐蚀速率最大的监检测点位同时进行现场数据采集,最终通过将近一年的监测数据分析表明:该条海管的腐蚀速率呈上升趋势,同时最大腐蚀速率为0.043mm/a,属中度腐蚀,需采取相对应的措施进行维护,最后通过计算得出:该条海底管道剩余寿命至少为247.5年。In 2023,the electromagnetic ultrasonic wall thickness monitoring technology was applied to the offshore section of a platform in an oil field group operation area in the eastern South China Sea to conduct real-time monitoring of its wall thickness.Firstly,based on the simulation data of flow accelerated corrosion and scouring corrosion,the monitoring points with the highest corrosion rate of the pipe were selected and field data were collected simultaneously.Finally,after nearly one year of monitoring data analysis,it was shown that the corrosion rate of the submarine pipeline showed an upward trend,with a maximum corrosion rate of 0.043mm/a,which was moderate corrosion and required corresponding measures for maintenance.Finally,through calculation,it was concluded that the remaining life of the submarine pipeline was at least 247.5 years.
