摘要: 油气管道风险评估是一项复杂的系统工程,为弥补传统风险评估方法应用于中国油气管道的局限性,提出一种名为“消极积极耦合风险评估”的新方法。该方法立足于中国管道实际工况,创新性地将提升管道安全的积极因素与构成威胁的消极因素置于同一评估框架,并着重分析其间的耦合作用机制,在研究中建立了失效可能性指标框架体系和失效后果指标框架体系,给出了具体的分值计算方法,并增加了耦合作用的修正指标值。通过西南地区某输气管道实例应用,验证了该方法的可行性与有效性,耦合作用对风险值的修正幅度在6%~14%。应用该方法可精准识别风险关键控制点,为风险缓解决策提供明确方向,从而有效预防中间事件与重大事故,对降低中国油气管道事故概率、保障能源动脉安全具有重要的实践指导意义。

Abstract: Oil and gas pipeline risk assessment is a complex systems engineering project. To address the limitations of traditional risk assessment methods when applied to China's oil and gas pipelines, this paper proposes a new method called“negativepositive coupling risk assessment ” . Based on the actual operating conditions of China's pipelines, this method innovatively integrates positive factors that enhance pipeline safety and negative factors that pose threats into the same assessment framework. It focuses on analyzing the coupling mechanism between these factors, establishes a framework system for failure probability indicators and a framework system for failure consequence indicators in the research, provides a specific score calculation method, and adds correction index values for coupling effects. Through the application of an example of a natural gas pipeline in southwest China, the feasibility and effectiveness of this method are verified. The correction range of the coupling effect on the risk value is between 6% and 14%. Applying this method can accurately identify key risk control points and provide a clear direction for risk mitigation decisions, thereby effectively preventing intermediate events and major accidents. It holds important practical guiding significance for reducing the accident probability of China's oil and gas pipelines and ensuring the safety of energy arteries.
