NMR imaging of materials for transport properties |
摘要 |
NMR imaging methods are provided for determining spatial diffusion coefficients, formation resistivity factors, mean pore size, and permeability of a porous material. The imaging methods employ a constant magnetic field and two images are obtained for the material, one with a non-imaging gradient and one without a non-imaging gradient. These images are combined to produce diffusion coefficients.
