摘　　要：低温胶凝原油管道启动过程中启动压力沿管长传递存在衰减现象。对低温胶凝原油管道启动压力传递过程中衰减现象的研究现状进行了总结,并对原油管道启动压力传递过程中衰减的原因进行了归纳、分析。结果发现,低温胶凝原油的压缩性对管线启动压力传递的衰减有重要影响。对现有考虑了原油可压缩性的启动模型进行了分析研究,并指出精确定量地描述低温胶凝原油的压缩性是管道再启动过程中亟待解决的关键问题。It is a fact that the pressure decreases along with pipeline in the start-up process of gelled crude oil under low temperature. The papei＂ summarized the current researches on the phe nomenon, and adopted induction analysis to search for the reason. It is found that gelled crude oil under low temperature is compressible, and its compression has significant influence on the quantitatively and accurately describe the compressibility of gelled crude oil under low temperature is a key problem to solve.
