Method and apparatus for multi-frequency NMR diffusion measurements in the presence of internal magnetic field gradients |
摘要 |
Pulse sequences are applied to a fluid in an earth formation in a static magnetic field having internal gradients. From the received signals, relaxation and diffusion characteristics of the fluid are determined. The determination takes into account the internal field gradients.
