摘      要：Enhanced oil recovery(EOR)has been widely used to recover residual oil after the primary or secondary oil recovery *** to conventional methods,chemical EOR has demonstrated high oil recovery and low operational *** have received extensive attention owing to their advantages of low cost,high oil recovery,and wide *** recent years,nanofluids have been widely used in EOR ***,several studies have focused on the role of nanofluids in the nanofluid EOR(N-EOR)***,the mechanisms related to N-EOR are unclear,and several of the mechanisms established are chaotic and *** review was conducted by considering heavy oil molecules/particle/surface micromechanics;nanofluidassisted EOR methods;multiscale,multiphase pore/core displacement experiments;and multiphase flow fluid-solid coupling *** can alter the wettability of minerals(particle/surface micromechanics),oil/water interfacial tension(heavy oil molecules/water micromechanics),and structural disjoining pressure(heavy oil molecules/particle/surface micromechanics).They can also cause viscosity reduction(micromechanics of heavy oil molecules).Nanofoam technology,nanoemulsion technology,and injected fluids were used during the EOR *** mechanism of N-EOR is based on the nanoparticle adsorption *** can be adsorbed on mineral surfaces and alter the wettability of minerals from oil-wet to water-wet *** can also be adsorbed on the oil/water surface,which alters the oil/water interfacial tension,resulting in the formation of *** are also adsorbed on the surface of nanoparticles,which reduces the asphaltene content in heavy oil,resulting in a decrease in the viscosity of oil,which helps in oil *** previous studies,most researchers only focused on the results,and the nanoparticle adsorption properties have been *** review presents the relationship between th
