Abstract :
Compared with the magnet of Nuclear Magnetic Resonance (NMR) Spectrometer that of Nuclear Magnetic Resonance Oil Well Logging is faced with some special difficulties. This paper begins with the explanation of these special difficulties, and then analyzes the main known borehole NMR logging apparatuses through strict calculations. Finally, this paper gives some useful clues to solve those problems existing in the designs.
