摘要
利用DN300工业试验环道,研究了启动压力波在管内原油中的传递规律。测量了不同操作条件下,启动压力波在原油中的传递速度,分析了启动流量、停输前油温、启输温度等因素的影响。试验和理论分析表明,利用原油的析蜡点温度、管道停输油温以及启动油温等参数,可更为直接地反映原油降温收缩性和胶凝原油本身的结构特性对启动压力波传递的影响规律。根据大型环道试验数据,通过数学回归得到了形式简单的启动压力波传递速度计算模型。
Transfer law of startup pressure wave in crude oil inside the pipe is researched by means of a DN300 Commercial Test Loop. Transfer velocity of startup pressure wave in crude oil is measured at different operating conditions, and influencing factors of startup flowrate. oil temperature before shutdown and startup transportation temperature are analyzed. Experimental and theoretical analyses show that influence law in cooling contractibility of crude oil and structure characteristic of gel crude oil itself on transfer of startup pressure wave can be more directly reflected through utilizing relative parameters such as wax deposited point temperature of crude oil and oil temperatures of pipeline at shutdown/startup. Simple form mathematical model for startup pressure wave transfer velocity is obtained through mathematical regression based on experimental data of the large-scale loop.
