HIGHLIGHTS (1) The NMR Amott method and the NMR T1–T2 spectrum spontaneous imbibition method were established, enabling wettability characterization at both macroscopic and pore scales. (2) The interbedded shale oil rocks in the Chang 7 Member of the Ordos Basin exhibit a mixed-wet characteristic with a preference for oil-wetting. (3) The mineral composition determines the oil-wet/water-wet tendency of the rock, while the pore structure controls fluid migration and distribution; together, they define the complex mixed-wettability characteristics of the rock.
