摘要: 受地质灾害、腐蚀缺陷、第三方破坏等因素的影响,油气管道在安全运输方面存在诸多隐患,因此研究埋地天然气管道泄漏扩散规律对泄漏点预测定位、应急预案制定具有重要的现实意义。通过对埋地天然气管道泄漏扩散过程进行数值模拟,分析了泄漏速度、风速以及环境温度对CH4体积分数的影响,总结了扩散规律。研究结果可为埋地天然气管道泄漏点准确定位及应急预案提供理论支撑。

Abstract: Because of geological disasters, corrosion defects, third party damage and other factors, there are many hidden dangers in the safe transportation of oil and gas pipelines. Therefore, it is of great practical significance to study the law of leakage and diffusion of buried natural gas pipelines for the prediction and location of leakage points and the formulation of emergency plans.Numerical analysis of the leakage and diffusion process of buried natural gas pipeline is carried out, the influence of leakage velocity, wind speed and environmental temperature on CH4 the methane concentration are analyzed and summed up diffusion law.The research results can provide theoretical support for the accurate location and emergency plan of the buried gas pipeline leakage point.

Key words: Buried pipeline, Leak, Diffusion, Numerical analysis
