Magnet assembly for nuclear magnetic resonance well logging tools |
| 摘要 |
A magnet assembly for nuclear magnetic well logging apparatus includes two diametrically opposed magnets which produce a static and substantially homogeneous magnetic field. Each magnet has a magnet axis and is partitioned into a first and a second magnet segment by a plane substantially parallel to the magnet axis.
