近年来不断发生天然气输送管道事故,其造成的人员伤亡、财产损失提醒人们确保管道安全运行的重要性。长北项目部天然气中央处理厂管道已运行数年,所属的埋地管道包括4条干线及16条支线,通过对埋地管道的风险评估,确定危险源的分布,得到了各段管道的泄漏风险值,提出了可使管道泄漏风险降低的措施,为生产过程中的安全提供了一定的保障,同时对埋地管道失效进行了预测,为管道安全运行提供了依据。
In recent years, natural gas pipeline accidents have occurred continuously, causing casualties and property losses, reminding people of the importance of ensuring the safe operation of pipelines. The natural gas central processing plant pipeline of Changbei Project has been in operation for several years. The subordinate buried pipelines include 4 main lines and 16 branch lines. Through the risk assessment of buried pipelines, the distribution of dangerous sources is determined and the leakages of various pipelines are obtained Risk value, put forward measures that can reduce the risk of pipeline leakage, provide some protection for the safety in the production process, and predict the failure of buried pipeline at the same time, which provides the basis for the safe operation of the pipeline.
