摘要:
针对管道沿线落差较大或变径时，水力瞬变对冷热原油顺序输送混油比例存在影响的问题，基于顺序输送混油理论，建立了冷热原油顺序输送混油控制方程。借助 FLUENT 软件对冷热原油途经变径管道水力瞬变过程进行数值计算，分析了输送顺序和流速对混油浓度的影响。研究表明：当冷热原油顺序流经渐缩管道时，混油长度增长较快，当冷热原油流经突扩管道时，混油长度增长速率降低。无论渐缩管道还是突扩管道，与前行俄罗斯油后行大庆油的输送方式相比，采用前行大庆油后行俄罗斯油的输送方式形成的混油段都较长，且突扩管段连接处和上游轴向各截面的平均混油比例波动较大。
Abstract:

The governing equation is established regarding the effect of hydraulic transient on the contamination ratio of the cold-hot contaminated crude oil batch transportation due to reduced pipeline or elevation. FLUENT software is applied to simulate the cold-hot crude oil passing through the reduced pipeline where the effect of the transportation sequence and the velocity are investigated. The study shows that the contamination length grows faster in the reduced pipeline，while the length grows slower in the expanded pipeline. The contamination lengths are large for both cases of Russian Oil first and Daqing Oil first. And，the contamination ratio vibrates at the joint location of an expanded pipeline with regard to the cross-sections on upstream pipeline.
