| description | Research on nanomaterials has opened up new opportunities for enhancing oil recovery. This paper reviews the mechanisms of nanomaterials for enhancing oil recovery, including reducing oil–water interfacial tension, regulating rock wettability, and decreasing crude oil viscosity, with a focus on the expansion of the oil-displacement mechanism of nano-silica. Nanofluids form interfacial nanolayers that diminish tension while altering surface wettability to promote oil stripping. Their structural disjoining pressure creates wedge-shaped films at oil–water–solid interfaces, driving droplet detachment. The synergistic “roll-up” and “diffusion” mechanisms improve oil mobility through capillary regulation and interfacial disturbance. These findings offer critical insights for optimizing nanomaterial applications in oil displacement systems, advancing fundamental research and technological development for enhanced recovery processes. |
