基于腐蚀防控的油田管道完整性技术管理体系构建与应用

Construction and Application of Pipeline Integrity Technology Management System Based on Corrosion Prevention and Control

随着萨南油田开发年限的增长,埋地管道腐蚀老化问题日益突出。为有效控制腐蚀,实现管道失效率控制目标,通过开展管道腐蚀因素分析,明确管道主要腐蚀类型、机理和影响因素,构建萨南油田管道完整性技术管理体系,并采取针对性腐蚀防控管理与技术措施。同时强化管道建设期、运行期完整性管理,使得管道腐蚀穿孔形势明显好转,失效率显著下降,降低了安全环保风险和产量损失。后续将持续细化开展管道完整性技术管理工作,以有效保障管道本质安全,助力上游业务提质、降本、增效和高质量发展。

With the growth of Sanan Oilfield development years,the problem of buried pipeline cor-rosion aging is becoming more and more prominent.In order to effectively control corrosion and achieve the pipeline failure rate control target,Sanan Oilfield carried out the analysis of pipeline corro-sion factors.Through the analysis,the main types,mechanisms and influencing factors of pipeline cor-rosion are clarified,a pipeline integrity technical management system is established,and targeted corro-sion prevention and control management and technical measures are taken.Through strengthening the integrity management of pipelines during construction and operation period,the situation of pipeline corrosion and perforation is significantly improved,the failure rate is greatly reduced,and the risk of safety and environmental protection and production loss are reduced.The subsequent continuous refine-ment and technical management of pipeline integrity can effectively guarantee the essential safety of pipe-lines,and help the upstream business to improve quality,reduce cost,increase efficiency,and devel-op with high quality.
