摘      要：This study investigated experimentally the coupled effects of hydrophilic SiO_(2) nanoparticles(NPs)and low-salinity water(LSW)on the wettability of synthetic clay-free Berea *** pressure,interfacial tension(IFT),contact angle,Zeta potential,and dynamic displacement measurements were performed at various NP mass fractions and brine *** *** of Mines(USBM)index was used to quantify the wettability ***,the NP stability and retention and the effect of enhanced oil recovery by nanofluid were *** results showed that LSW immiscible displacement with NPs altered the wettability toward more water *** the decreasing brine salinity and increasing NP mass fraction,the IFT and contact angle *** wettability alteration intensified most as the brine salinity decreased to 4000 mg/L and the NP mass fraction increased to 0.075%.Under these conditions,the resulting incremental oil recovery factor was approximately 13 percentage *** the brine salinity was 4000 mg/L and the NP mass fraction was 0.025%,the retention of NPs caused the minimum damage to permeability.
