Abstract
Apparatus is provided for measuring weight and torque on the drill bit in a logging-while-drilling system. The upper end of the drill bit is adapted for slidable engagement with the lower end of the drill collar. Transducers are mounted with a cavity formed between the drill collar and drill bit when they are in slidable engagement. The transducers measure axial and rotational motions of the drill bit which represent weight and torque on the drill bit, respectively.
