Latest Patents
Du's most recent inventions include two notable patents that address improvements in NMR logging instruments. The first patent details a **nuclear magnetic resonance logging instrument probe with double-layered magnets and an antenna excitation method**. This invention introduces a probe framework that includes a shielding layer, where multiple main magnets are strategically positioned above and below the shielding layer. By ensuring that the central axes of these magnets remain parallel and maintaining precise distances, this design enhances the circumferential recognizing capability of the probe, allowing for three-dimensional detection of stratum (radial, axial, and circumferential).
The second patent is for a **nuclear magnetic resonance logging instrument probe with multi-layered magnets and an antenna excitation method**. This innovation features a cylindrical probe skeleton housing multiple magnet assemblies that are distributed circumferentially. Each assembly comprises at least two magnet layers magnetized oppositely, and antennas positioned outside each assembly allow for independent feeding. This design facilitates detection of stratum information at various azimuth angles, thereby significantly improving the probe's circumferential resolution and enabling comprehensive three-dimensional detection.
