摘　　要：西江海底输油管道在发生泄漏后立即停产,其管道内残余原油随着时间的推移将逐渐凝固,从而导致管道堵塞,无法使用。通过对西江管道残留原油回收技术原方案和新方案的分析和实践,发现新技术方案相比于原方案,在施工难度、作业风险、原油回收效率等方面有较大优势,为国内海洋工程技术提供了宝贵的经验,并对其他类似项目提供指导和帮助。Production will be stopped immediately after a leak on the Xijiang subsea oil pipeline.Residual crude oil in its pipeline will gradually solidify over time,resulting in pipeline blockage and unusability.Through analysis and practice of the original and new schemes of the Xijiang pipeline residual crude oil recovery technology,it is found that the new technical scheme has greater advantages in terms of construction difficulty,operational risk,and crude oil recovery efficiency than the original scheme.The results provide guidance and valuable experience for other similar projects.
