    黄土边坡下不同敷设角度对油气管道影响及评价方法研究

    EFFECTS OF OIL AND PIPELINE LAYING IN DIFFERENT ANGLES AT LOESS SLOPE AND EVALUATION METHODS

    • 摘要: 近年来,随着油气储运技术的发展,管道已经日益在各种地质地貌复杂的区域和各种特殊地理环境中成功的进行了敷设。但湿陷性黄土地区和山体滑坡地区等特殊管段,油气管道会受到条件的制约,甚至在铺设或运营过程中出现种种问题。本文在力学分析与计算的基础上,通过建立力学模型;结合相似模拟实验分析管道在边坡按不同角度敷设,水流冲刷对油气管道的影响作用;同时借鉴国外管道风险评价技术的基本思想和处理方法,建立了黄土地区特殊管段的风险评价方法,研究对黄土区的管道铺设具有一定指导意义及参考价值。

       

      Abstract: In recent years, with the development of storage and transportation of hydrocarbon technology. The pipeline has been laid successfully in a variety of complex geomorphology areas and a variety of special geographical environment. But in some special pipe section, such as Collapsible-Loess Area and Mountain-Landslide Area, oil and gas pipeline is restricted by some factors. Even there will be found a variety of problems in the course of laying or operating. In the paper, we will based on mechanical analysis and calculation, and established mechanics model, combined with the similarity simulation experiment, analysis the effect of water flow on oil and gas pipeline where laid at different angles in slope, and referenced the theory and method of pipeline risk-assessment of foreign countries. The risk assessment method of special pipeline section is established in loess area. The result has reference value and guidance significance to the pipeline laying in the loess area.
