基于完整性数据优化的油气管道维护维修管理

Management on repair and maintenance of oil/gas pipeline based on integrity data optimization

针对传统的油气管道管理仅依靠经验实施治理工作,维修资金处于"一刀切"的初级水平,维修不彻底,甚至存在个别高风险点遗漏治理的问题,提出了基于完整性数据优化的油气管道维护维修管理方法:在全面实施管道完整性管理的基础上,依托其收集和整合的油气管道基本信息、日常运行、管道沿线环境、风险评价等海量数据,通过综合分析制定科学的工程计划,对其实施有效的维修维护,依据管道风险的发生概率及失效后果进行资源分配,从而确保将有限的资金投入到最需要维修维护的管道上。实例应用结果表明:该方法操作简单,在保证风险削减的前提下,可以降低不必要的投资成本。

Under traditional management on oil/gas pipelines, treatment is made with experiences, maintenance is not thorough with allocation of required capitals in the primitive ＂One-size-fits-all＂ manner, or even some high-risk points are neglected. To solve these problems, a management approach for repair and maintenance of oil/gas pipelines based on integrity data optimization has been proposed. In detail, based on massive data of oil and gas pipelines, including basic information, routine operation parameters, environmental conditions along the pipelines, and risk assessments, acquired and integrated by pipeline integrity management system, through comprehensive analysis, scientific engineering plan is formulated to realize effective maintenance and repair. Moreover, resources are allocated considering probability of relevant risks and consequences of failure, so that limited capitals can be designated to pipelines that require immediate repair and maintenance. Application results show that the approach is simple and can help to effectively minimize unnecessary expenditures without sacrificing risk reduction.
