Numerical simulation of nuclear magnetic resonance in saturated porous media with consideration of phase motion

A method to perform the numerical simulation of Nuclear Magnetic Resonance (NMR) for porous media saturated with a multicomponent fluid with consideration of phase motion is proposed. This method is applied to numerical models of porous media whose fluid component distribution is determined by the direct hydrodynamic simulation using the density functional method. Numerical results for NMR signals obtained for various pulse sequences and their usage for the transport description of fluid in porous media are discussed. Flow propagators for various flows are calculated. The flow propagators and the results obtained during passive admixture simulation are compared.
