| Summary: | 0.15 mm 2 . The slice thickness is 5 mm. The data were then a cylindrical pipe and glass bead packs. Two dimensional a narrow pulse approximation concept was applied so that the analyzed to find the localized velocities. The result showed arbitrary cross sections with pixel sizes of the order of because the relaxation times for fluids in porous media are been carried out to measure velocities for fluid flows inside can provide information about how fluid is transported in catalytic chemical reactions involve the flow of fluids derived for the proposed velocity imaging method. Compared estimating absolute permeability which is an important field gradient approach was proposed to measure the localized For many years, there has been a considerable interest by the images of the related phase shift values were obtained in Imaging to velocity measurement. A stimulated echo pulse investigated the application of Nuclear Magnetic Resonance Many important processes such as petroleum production and method allows longer observation time which is crucial oil industry and geologists in the measurement and the porous media. Furthermore, it provides the possibility of prediction of flow permeability in rocks. We have property used in modeling the flow of fluids in porous media. that the method we proposed is appropriate for measuring the the entire observation time. Preliminary experiments have through porous media. The measurement of localized velocity to the spin-echo pulsed field gradient method, the proposed velocities of spins don't have to be assumed constant during velocities. velocity in porous media. The velocity estimation model was very small and the NMR signals decay very fast. Furthermore, |
