摘　　要：凝油粘壁现象常会对地面集输管道的安全流动保障造成影响。目前凝油粘壁的研究方法与粘附作用机理尚不明确,为此系统调研了国内外原油界面特性与粘附作用的研究进展,对现阶段较为成熟的粘附作用理论与模型进行了梳理与对比,讨论了原油界面特性与粘附作用的影响因素,并总结了当下较为适用的界面特性实验设备与测试分析方法,特别就目前较为新颖的分子动力学模拟在原油界面特性与粘附的研究展开了探讨。最后给出开展原油管壁粘附作用机理研究的几点思考与启示,这将对进一步揭示低温集输凝油粘壁机理具有指导意义。Wall sticking of condensate oil always has influence on the pipeline flow assurance in surface gathering and transportation.Presently,the research methods and adhesion mechanism for wall sticking of condensate oil are not clear.Thus,the systematic investigation was performed for the progress of research on the interfacial behavior and adhesion of crude oil at home and abroad,and the current mature adhesion theories and models were combed and compared.Besides,the influencing factors of the interfacial behavior and adhesion of crude oil were discussed,and the current applicable experimental equipment and test analysis methods for interfacial behavior were summarized.In particular,the research on the interfacial behavior and adhesion of crude oil by molecular dynamics simulation was also discussed.Finally,some thoughts and enlightenment were given for the study on the wall sticking mechanism of crude oil,which will be of great significance to further reveal the wall sticking mechanism of condensate oil in low-temperature gathering and transportation.
