Rotating Downhole Logging Tool with Reduced Torque

摘要

Systems and methods for reducing torque on a rotating downhole logging tool are provided. In one embodiment, a downhole logging tool is provided. The downhole logging tool may include a support element, which may include a hollow cavity. The support element may be configured to rotate about an axis when the support element is inserted in a well, and the hollow cavity may be configured to permit fluid flow through the support element when the support element is in the well. Furthermore, the downhole logging tool may include a first fairing portion, which may include a first sensor to obtain measurements in the well. Additionally, the first fairing portion may be configured to form a revolution surface associated with a portion of the support element to reduce fluidic resistance of the rotating support element.
