Zusammenfassung:	The invention discloses a method for establishing a three-water-component difference parallel conductive water saturation model, and relates to the field of oil and gas field exploration and development. The method comprises the following steps: acquiring pore structure parameters of a rock core sample by utilizing a rock physical experiment, performing a multistage centrifugal force nuclear magnetic resonance experiment on the rock core sample, acquiring a multistage centrifugal force nuclear magnetic resonance T2 spectrum of the rock core sample, establishing a strong and weak bound water boundary model, and then performing a rock electricity experiment on the rock core sample. The method comprises the following steps: analyzing a differential conductivity rule of a strong bound water component, a weak bound water component and a free water component in rock, constructing a comprehensive three-water-component differential parallel conductive cementation index item, dissecting rock electricity parameters of
