摘　　要：山区输油管道因跨越复杂的地质环境,易受自然灾害和第三方施工等多种风险因素影响。为揭示山区输油管道泄漏扩散规律及地形对泄漏路径的影响,提出科学的溢油拦阻布控方案,为泄漏防控和应急响应提供理论支持,基于数字高程模型(digital elevation model,DEM)和计算流体力学(computational fluid dynamics,CFD)技术,结合真实地形数据,对复杂山区地形下输油管道泄漏进行数值模拟。通过模拟不同内压条件下泄漏油品的扩散路径,定性分析地形起伏和地表特征对扩散规律的影响,同时,定量研究泄漏面积与管道内压之间的非线性关系。研究发现,泄漏油品的扩散路径受山区地形高差和地表特征显著影响,内压增大时,扩散范围呈非线性增长趋势。结合数值模拟,提出了山区输油管道泄漏拦阻布控方案,可为提高山区输油管道泄漏防控能力提供借鉴。Oil pipelines in mountainous regions are vulnerable to natural disasters,third-party construction,and other risk factors due to the complex geological environment.To understand the diffusion patterns of oil pipeline leakage and the impact of terrain on leakage paths,a scientifically-grounded oil spill containment and control scheme was developed to support leakage prevention and emergency response.Utilizing the digital elevation model(DEM)and computational fluid dynamics(CFD)technology,along with real terrain data,the numerical simulation of oil pipeline leakage in complex mountainous terrain was conducted.The diffusion paths of leaked oil were simulated under varying internal pressure conditions to qualitatively analyze the effects of topographic relief and surface characteristics on the diffusion pattern.Additionally,the nonlinear relationship between leakage area and pipeline internal pressure was quantitatively examined.The findings indicated that the diffusion path of leaked oil is significantly affected by the elevation differences and surface features of mountainous terrain,with an observed nonlinear growth trend in diffusion range as internal pressure increases.A leakage containment and control scheme for oil pipelines in mountainous regions was proposed,incorporating numerical simulation to enhance leakage prevention and control capabilities.
