| 摘要 |
A method for measuring nuclear magnetic properties (NMR) properties of a formation, the method including applying a magnetic field to nuclei of the formation during a polarizing interval, the magnetic field having a polarizing intensity; changing the magnetic field to a measurement intensity, the measurement intensity applied to the nuclei of the formation during a measurement interval; applying to the formation at least one radio frequency (RF) pulse train during the measurement interval; and measuring an NMR signal from the formation.
