Optimization of magnet arrangement for nuclear magnetic resonance well logging tools
29 Jun 21
A method for fabricating a magnet on a nuclear magnetic resonance logging tool includes identifying a desired magnetic field strength at a predetermined depth of investigation, receiving a set of magnet segments configured for deployment on the logging tool in a magnet arrangement which make up a magnet array on the logging tool, processing a magnetic strength and an angular offset of selected magnet segments and their unique location in the magnet array to compute corresponding magnetic field strength solutions at the predetermined depth of investigation, selecting one magnet arrangement solution that minimizes a difference between the magnetic field strength solution and the desired magnetic field strength at the predetermined depth of investigation, and deploying the magnet segments on the logging tool according to the selected magnet arrangement solution to fabricate the magnet.
