基于SPS的原油管道最大再启动压力增加值分析

分析了现有研究停输再启动过程方法的优缺点,采用仿真模拟软件SPS进行最大再启动压力增加值的影响因素分析。首先建立了西部某原油管道仿真模型,通过与现实工况对比,验证了模型准确性。然后在管道模型基础上进行停输再启动工况模拟,得到管道最大再启动压力增加值位置,并通过修改停输时间、管内径、管长、管道弹性模量、油品体积模量、油品密度、再启动原油温度得出各因素对最大再启动压力增加值的影响。最后通过统计分析软件SPSS进行Kendall、Spearman两种相关系数的计算,得出各因素影响程度排序。

Analysis of Maximum Restart Pressure Incrementof Crude Oil Pipeline Based on SPS

The advantages and disadvantages of the existing methods to study the shutdown and restart process were analyzed,simulation software SPS was used to analyze the influencing factors of maximum restart pressure increment.The simulation model of a crude oil pipeline in the west of China was established.And the accuracy of this model was verified by comparing with the actual working conditions.Then based on the pipeline model,the simulation of shutdown and restart conditions was carried out,and the maximum restart pressure increment position of the pipeline was obtained.The influences of various factors on maximum restart pressure increment were obtained by modifying the stop time,pipe diameter,pipe length,elastic modulus of pipelines,bulk modulus of oil,oil density,and the starting temperature of the crude oil.Finally through the statistical analysis software SPSS,two correlation coefficients of Kendall and Spearman were calculated,and the influence degree of each factor was obtained.
