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 (200) may include a support element (202), which may include a hollow cavity (226). The support element may be configured to rotate about an axis(214) 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 (212A), which may include a first sensor (210A) 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.
