基于Phast-QRA的某油田拉油点密闭储油罐闪燃事故后果模拟分析

SIMULATION AND ANALYSIS OF CONSEQUENCES OF FLASH FIRE ACCIDENT IN CLOSED STORAGE TANKS IN AN OILFIELD BASED ON PHAST-QRA

采用Phast-QRA软件对某拉油点密闭储油罐发生的闪燃事故进行事故后果模拟定量分析。根据事故发生时的场景及相关参数通过软件模拟计算出密闭储油罐在发生事故的死亡半径、重伤半径和轻伤半径等参数,模拟计算出事故的最大影响范围和严重程度,提出预防事故的安全技术和管理建议对策措施,为避免同类事故发生提供理论基础,为密闭储油罐的安生产运行提供技术支撑。

Phast-QRA software was adopted to simulate and quantitatively analyze the consequences of a flash ignition accident occurred in a closed oil storage tank at a vehicle oil transportation worksite.According to the scene at the time of the accident and the related parameters,the radius of death,serious injury and minor injury of the closed storage tanks in the event of an accident is calculated through software simulation.The paper simulates and calculates the maximum influence range and severity of the accident.It puts forward the safety technology and management suggestions and countermeasures to prevent accidents.This provides the theoretical basis for avoiding the occurrence of similar accidents and the technical support for the safe production and operation of the closed oil storage tanks.
