摘　　要：当前,为预防原油储罐火灾事故,油气生产企业更多关注的是生产及作业过程中出现的事故,诸如明火、静电、雷电等引起的事故,而对工艺系统本质安全考虑较少。基于"本质安全"理论,从研究原油储罐火灾模式及形成发展过程入手,结合常规油气生产运行条件及管理方式,借鉴现有的工艺技术,充分考虑惰性气体对爆炸混合气体失爆的影响,提出了实现固定顶原油储罐全密闭储存的工艺设计思路,并提出应加强运行与维护管理,以提高系统本质安全水平。At present,oil and gas producers pay more attention to the accidents caused by open flame,static electricity,lightning strikes and so forth emerging during the process of production and operation so as to prevent fire accidents of crude oil tank.Yet less consideration is given to intrinsic safety of the system.Based on the theory of intrinsic safety,this paper begins with the research on the modes,formation and development process of fire of oil tank.And then combining with the operation conditions and management methods of regular oil and gas production,the paper learns from the existing technologies and takes full account of the impacts of inert gases on explosive mixed gas explosion.It brings forward the process design ideas to realize fully-enclosed storage of fixed-roof oil tank.
