- 摘要:
- 中俄原油管道是中国第一条穿越高寒区的大型管道工程。高寒区管道运行维护面临的主要问题是冻土地质灾害、低温维抢修和腐蚀防护等。中国缺少高寒区管道运行维护实践经验,而加拿大、美国和俄罗斯已在高寒冻土区建设多条油气管道。国内外高寒区管道运行维护面临的推荐做法包括实施管道冻胀融沉防治和位移监测,定期进行管道内检测评估管道状况,研制冻土、沼泽特殊环境专用维抢修设备,应用无人机巡线和牺牲阳极阴极保护等。未来高寒区管道设计建设的发展方向是全生命周期免维抢、设备远程控制和数字化管理。借鉴国外管道先进实践经验有助于提升中国高寒区管道运行维护技术水平,并为中俄东线管道项目提供借鉴。
Sino-Russia crude oil pipeline was the first large-scale pipeline project in China crossing the cold area.The pipeline operation and maintenance in high cold areas were plagued by permafrost geological disaster, low temperature and corrosion.China lacks practical experience in pipeline operation and maintenance in cold areas, however, Canada, the United States and Russia have built several oil and gas pipelines in permafrost regions.In this paper, the recommended practices for pipeline operation and maintenance at home and abroad were introduced, such as the implementation of pipeline frost heave and thaw settlement prevention and displacement monitoring,the regular in-line inspection and evaluation of pipeline conditions,the development of special maintenance and repair equipment for special environment as frozen soil and swamp, the application of UAV line patrol and sacrificial anode cathodic protection.It was pointed out that the development direction of pipeline design and construction in the future was maintenance free, remote control of equipment and digital management.By learning the advanced practical experience of foreign pipelines，it is helpfulto upgrade the technical level of pipeline operation and maintenance in China's cold areas, and provides reference for Sino-Russia east pipeline project.
