【摘要】 由地震引发的各种次生地质灾害,对兰-成-渝管道的安全运输造成了严重的威胁。为了保护管道的安全及灾区的成品油供应,中国石油天然气管道分公司在管道抢险工作中,应用了完整性管理技术,用于识别影响管道安全的威胁因素及分布状况。准确评价了风险等级,进行了现场检测与评估,制定了合理的预防和减缓措施,提出管道修复方案,并采用基于GIS的完整性管理系统,将识别和评价结果做成各种专题图供现场抢险人员使用。发挥了完整性管理系统在基础数据管理与共享、风险识别和评价方面的作用,实现了完整性管理在应对突发灾害方面的应用。更多还原

【Abstract】 The earthquake occurred in Wenchuan County of Sichuan Province resulted in seriously secondary geological disasters such as landsides and quake-formed lake.The Lan-Cheng-Yu pipeline passing through the earthquake area had also been seriously affected.For protecting the pipeline safety and supplying oil for disaster area,the PetroChina Pipeline Company applied the integrity technology to identify the threats affecting the pipeline safety and assess the risk grade.The protection and mitigation plans were developed.An integrity management program based on GIS was also used to graphically display the assessment results and provide information for operators to effectively allocate resources for appropriate prevention,detection and mitigation activities of safety improvement.更多还原
