摘要: 为降低油气集输站场事故风险,利用风险矩阵叠加技术研究油气集输站场安全风险情况。首先,基于沸腾液体扩展蒸气爆炸(BLEVE)模型和修正的超压准则分析危险源的伤害程度,确定其死亡区、重伤区、轻伤区以及安全区的伤害区域;其次,引入笛卡尔距离矩阵和网格划分技术,构建站场区域内各危险源的死亡概率矩阵,并通过各危险源的设备风险值和叠加原理求得区域网格风险矩阵;然后,采用英国焊接学会(TWI)修正的风险分级原理,绘制站场区域风险等级图;最后,通过确定新疆某油田集输站场的个人风险可接受准则,量化站场区域风险的可接受程度。结果表明:个人风险矩阵分析方法能够明确站场区域内各位置处的安全风险情况,提高站场安全管理水平。

Abstract: In order to reduce accident risks in oil and gas gathering and transportation stations, situation of these stations is studied by using risk matrix superposition technology. Firstly, damage degree of hazard sources was analyzed based on boiling liquid extended vapor explosion (BLEVE) model and revised overpressure criteria, and damage areas of death zone, severe injury zone, light injury zone and safety zone were determined. Secondly, death probability matrix of each danger source was constructed by introducing Cartesian distance matrix and grid division technology, and regional grid risk matrix was obtained through equipment risk value and superposition principle of danger sources. Then, regional risk level map of station was drawn using risk classification principles modified by British welding society (TWI). Finally, with an oilfield gathering and transportation station in Xinjiang as example, acceptability of regional risk was quantified by determining its personal risk acceptability criteria. The results show that personal risk matrix analysis method can clarify security risk situation at various locations within station and improve its safety management.
