摘要

本文研究了与蒸馏水相比，含水石墨烯悬浮液通过含油饱和岩心样品降低渗透率的机理。实验数据分析表明，渗透率的增加是由于两种不混相流体在相互运动时在界面处形成波纹膜所致。波纹表面的出现是石墨烯-纳米流体-碳氢化合物界面处开尔文-亥姆霍兹不稳定性的结果。结果还表明，只有在过渡层-石墨烯薄膜存在的情况下才有可能发生不稳定性。

INCREASE IN THE PERMEABILITY OF A MICROCAPILLARY WITH WALLS COATED WITH CORRUGATED GRAPHENE FILM

The paper considers the mechanism of reducing the permeability of aqueous graphene suspension through an oil-saturated core sample compared to distilled water. Analysis of experimental data shows that an increase in permeability is due to the formation of corrugated films at the interface between two immiscible fluids during their mutual motion. The appearance of wavy surfaces is the result of Kelvin–Helmholtz instability at the graphene–nanofluid–hydrocarbon interface. It is also shown that the occurrence of instability is possible only in the presence of a transition layer—graphene film.
