Claim 5:
6. The method for measuring fluid saturation in nuclear magnetic resonance (NMR) on-line displacement according to claim 1, characterized in further comprising: correcting the fluid saturation of the on-line displacement system, including:
measuring a nuclear magnetic resonance (NMR) T2 spectrum under the dead volume filling of the on-line displacement system as displacing phase fluid and the core to be measured that is saturated with the displaced phase fluid, to generate an initial T2 spectrum;
correcting the fluid saturation of the on-line displacement system according to the initial T2 spectrum, the calibrated T2 spectrum and the displacement process T2 spectrum.
