Abstract:

Low logging speed is one of the main problems faced by nuclear magnetic resonance logging. A useful way to solve this problem is to make proper improvements on the design of the magnet system of the nuclear magnetic resonance logging instrument. In view of this, two realization methods of fast nuclear magnetic resonance logging (pre-polarization method and accelerated polarization method) have been theoretically studied and derived in this article. They are helpful for the design of the magnet system of the nuclear magnetic resonance logging instrument. Calculations and analyses show that the two methods can really be of service to the improvement of logging speed.
