事故树分析方法在油气集输H2S中毒事故中的安全评价分析

Analysis on Safety Assessment of Accident Tree Analysis in H2S Poisoning Accident of Oil and Gas Gathering and Transportation

油气集输系统工艺复杂,仪器和流程众多,生产连续性强,在系统运行过程中,一旦某一环节或步骤出现问题,轻则影响油气集输系统的正常生产,重则造成重大的人员伤亡和财产损失,因此,对油气集输系统进行安全评价具有重要意义。主要运用事故树分析方法对油气集输系统中的H2S中毒事故进行了安全分析和评价。

Oil and gas gathering and transportation system has complex technology,numerous instruments and processes,and strong production continuity.In the process of system operation,once a problem occurs in one link or step,it will affect the normal production of oil and gas gathering and transportation system slightly,and cause heavy casualties and property losses.Therefore,oil and gas gathering and transportation system is safe.Evaluation is of great significance.This paper mainly uses fault tree analysis method to analyze and evaluate the safety of H2S poisoning accident in oil and gas gathering and transportation system.
