Apparatus and technique for NMR diffusion measurement. |
摘要 |
<p>A method for conducting borehole NMR measurements comprising the steps of: providing a magnetic field and a magnetic field gradient at a desired location along a borehole; carrying out at least one NMR experiment in the presence of the magnetic field gradient; sensing the diffusion effect on the decay of at least the first echo; and determining therefrom the diffusion coefficient. Apparatus for carrying out the method is also described. <IMAGE></p> |
