Abstract: 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.(2 Figures, 3 Tables, 95 References)
