Well-Logging Tool With Azimuthal And Spectral Radiation Detectors And Related Methods

摘要

A well-logging tool may be positioned within a borehole of a subterranean formation. The well-logging tool may include a housing having an interior defining a dual-detector receiving chamber extending longitudinally, and having first and second portions, and a first azimuthal radiation detector carried by the first portion of the dual-detector receiving chamber. The first azimuthal radiation detector may include a first gamma-ray detector and a first photodetector associated with the first gamma-ray detector. The well-logging tool may include a second spectral radiation detector carried by the second portion of the dual-detector receiving chamber. The second spectral radiation detector may include a second gamma-ray detector and a second photodetector associated with the second gamma-ray detector.

1. A well-logging tool to be positioned within a borehole of a subterranean formation, the well-logging tool comprising:
a housing having an interior defining a dual-detector receiving chamber extending longitudinally, and having first and second portions; a first azimuthal radiation detector carried by the first portion of the dual-detector receiving chamber, said first azimuthal radiation detector comprising a first gamma-ray detector and a first photodetector associated therewith; and a second spectral radiation detector carried by the second portion of the dual-detector receiving chamber, said second spectral radiation detector comprising a second gamma-ray detector and a second photodetector associated therewith; wherein said second gamma-ray detector is larger than said first gamma-ray detector.
