Risk assessment and protection reinforcement technology for geological hazard sections of long-distance oil and gas pipelines

摘要

我国长输油气管道多途经山区、黄土区、岩溶区等地质条件复杂地段，滑坡、黄土湿陷、泥石流等地质灾害频发，严重威胁管道运行安全与油气资源稳定供应。为开展地质灾害易发区管道风险评估、提升管道防灾加固效率，本文结合外业地质调查，综合运用监测与数值分析方法，构建灾害易发区管道风险管理体系，分析各类地质灾害作用下管道的失效模式，研究配套防灾加固技术。研究成果可用于长输油气管道地质灾害易发区识别与风险等级评估，提供高效技术手段降低管道运行风险，保障管道安全稳定运行，为地质灾害易发区长输油气管道风险管控与治理提供技术思路。

Abstract

China’s long-distance oil and gas pipelines often pass through complex geological conditions such as mountainous areas, loess areas, and karst areas. Geological disasters such as landslides, loess subsidence, and mudslides occur frequently, seriously threatening the safety of pipeline operation and the stable supply of oil and gas resources. In order to carry out risk assessment of pipelines in areas prone to geological disasters and improve the efficiency of pipeline disaster prevention and reinforcement, this article combines field geological surveys, comprehensively uses monitoring and numerical analysis methods, constructs a pipeline risk management system in disaster prone areas, analyzes the failure modes of pipelines under various geological disasters, and studies supporting disaster prevention and reinforcement technologies. The research results can be used for identifying and assessing the risk level of geological hazards in long-distance oil and gas pipelines, providing efficient technical means to reduce pipeline operation risks, ensuring safe and stable pipeline operation, and providing technical ideas for risk control and governance of geological hazards in long-distance oil and gas pipelines.
