关于老龄管道的安全运行

0n Safe Operating of Ageing Oil and Gas Pipelines

管道老龄化是世界性问题,进入老龄期的管道能否继续安全运行,需要从管道的原始条件、维护条件及油田的产量方面进行综合考量。美国贯穿阿拉斯加管道是老龄管道继续安全运行的成功范例,借鉴其成功经验,可以促进与保证东北原油管网的安全运行。对于东北管网庆铁线交替输送中俄原油方案,认为必须对管道的原始条件和管道的应力交变问题进行仔细调查与研究,慎重决策。

The author considers that the ageing of oil/gas pipeline is a global issue, and operators should comprehensively take pipeline's original condition and maintenance condition as well as oilfield production into account to determine whether the pipeline at ageing stage could continue to operate safely. Take Trans-Alaska Pipeline System (TAPS) for example, the paper introduces TAPS's original condition, maintenance condition and economic factors and service life, and points out that TAPS's successful experience in operating ageing pipeline can be referenced for the purpose of promoting and ensuring safety operation of China's Northeast Oil Pipeline Networks. For the program worked out for intermittently transporting Daqing crude and Russian crude through QingTie Oil Pipeline, the author presents the viewpoint that the problems in pipeline's original condition and stress/strain should be investigated and studied thoroughly so as to make decision carefully.
