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 employ constant magnetic field two images obtained the material, one with non-imaging gradient without gradient. These combined to produce coefficients.
