主　　题：Wettability alteration Retention Silica nanoparticle Surface modifcation Enhanced oil recovery 

摘      要：Enhanced oil recovery(EOR)processes are applied to recover trapped or residual oil in the reservoir rocks after primary and secondary recovery *** the wettability of the rock from oil-wet to water-wet is named wettability *** is an important factor for *** to their unique properties,nanoparticles have gained great attention for improving oil *** the promising results,the main challenges of applying nanoparticles are related to the colloidal stability of the nanofuids in the harsh conditions of the *** recent years,polymer-grafted nanoparticles have been considered as novel promising materials for *** obtained results showed that adding a hydrophobic agent trimethoxy(propyl)silane on the surface of modifed silica nanoparticles with polyethylene glycol methyl ether has an efective role in improving retention and wettability alteration,especially in the oil-wet substrate due to hydrophobic *** modifed silica nanoparticle by mixed polyethylene glycol methyl ether(Mn~5000)and trimethoxy(propyl)silane showed a proper performance at a concentration of 1000 ppm and a salinity range of 2000-40,000 *** obtained fndings can help for a better understanding of the silica nanofuid modifcation with both hydrophilic and hydrophobic agents for the EOR application of near-wellbore.
