摘　　要：针对中国石油化工股份有限公司胜利油田分公司胜利埕岛油田(以下简称胜利埕岛油田)47条海底管线急需进行检测评价、但目前国内外海底管线检测技术研究与应用尚不成熟的现状,通过综合各种腐蚀检测、分析与控制技术的优势,为在役及新建海底管线提出了相应的腐蚀检测、控制与管理方案。包括:平台采出液腐蚀性测试与缓蚀剂评价;管线内检测及水下成像技术检测海底管线的腐蚀、损伤、变形与悬空;海底管线防腐蚀选材设计以及管线基础液化监测等。The 47 subsea pipelines in Shengli Chengdao Oil Field are badly in need of corrosion detection and evaluation. Whereas the detection technologies developed for the subsea pipelines and their applications are not commercially proven. A detection and control schemes are proposed for both operating and newly - built subsea pipelines based upon the corrosion detection experience and optimization of analysis and control technologies, such as testing of corrosiveness of platform production streams and corrosion inhibitor evaluation, the internal corrosion of subsea pipelines, the detection of corrosion, damages, deformation and overhang of subsea pipelines by underwater imaging technology, and proper selection of pipeline materials and pipeline foundation liquefaction monitoring, etc.
