Asphaltene deposition on rock surface seriously affects oil recovery efficiency. Molecular dynamics simulation method is used to study the difference in the adsorption behavior of asphaltene molecules on quartz surface, which will help to improve the in-depth understanding of asphaltene microstructure. This study finds that electrostatic interaction is an influential factor affecting asphaltene deposition on rock surface. We also illustrated the different adsorption behaviors of different asphaltene molecules and the influence of rock surfaces on the deposition.
