Spontaneous imbibition of nanofluid has attracted much interest in enhanced oil recovery (EOR) in ultralow permeable reservoirs. However, the oil distribution in ultralow permeable cores during the spontaneous imbibition using nanofluids has not been discussed in detail. In this study, imbibition experiment and nuclear magnetic resonance (NMR) measurement were used to monitor the migration rule of nanofluid and oil distribution in the imbibition. The results show that 70.82–71.98 wt% of the oil was distributed in mesopores (50 nm
