摘要:
A system for acquiring directional information about a geologic formation includes at least one directionally sensitive nuclear magnetic resonance (NMR) assembly disposed at a borehole string including the downhole component. The at least one NMR assembly includes at least one magnet configured to generate a static magnetic field and at least one coil configured to generate an oscillating magnetic field, the at least one NMR assembly configured to perform an NMR measurement of at least one sector of a formation region. The system also includes a processing device configured to receive NMR measurement data from the at least one NMR assembly. The processing device is configured to analyze the NMR measurement data to estimate a parameter of the sector, determine a direction of the downhole component based on the estimated parameter; and steer the downhole component according to the determined direction.
