摘要 利用SPS仿真软件建立正反输仿真模型,对处于低输量工况的阿赛线管道进行正反输运行模拟,并研究了正反输过程中沿线油温随时间的变化规律,以及反输输量对反输温降的影响。结果表明,正输稳态下沿线油温逐渐降低;反输开始沿线油温先降低后升高,达到稳态后油温逐渐降低;反输进站油温先降低后稍有升高,最终趋于稳定;明确了正反输过程中原油最低温度为存留原油被完全推出管道时的进站温度;反输输量越大,反输过程中的最低油温越高,达到反输稳定状态也更快。通过SPS仿真软件模拟分析得出的正反输工艺温度变化可为确定阿赛线正反输运行方案提供一定依据。 The forward and reverse transportation simulation model was established by using SPS simulation software to simulate the forward and reverse operation process of A-Sai crude oil pipeline at low throughput.The change law of the oil temperature along the pipeline during the process of forward and reverse transportation is studied.The results show that the oil temperature along the pipeline decreases gradually under the steady state of forward transportation.The oil temperature drops first and then increases at the beginning of the reverse transportation,and then drops gradually after reaching the steady state.The oil temperature at the reverse inlet station decreases first and then increases slightly,and finally tends to be stable.The lowest temperature of crude oil in the process of forward and reverse transportation is the arrival temperature when the remaining crude oil is completely pushed out of the pipeline.In addition,the influence of inverse throughput on oil temperature drop during the inverse transportation was analyzed.The higher the inverse throughput is,the higher the lowest oil temperature in the process of inverse transportation is,and the faster the stable state of inverse transportation reaches.The temperature change of forward and reverse transportation obtained by SPS simulation analysis can provide certain basis for making the forward and reverse transportation scheme of A-Sai pipeline.
