Abstract
A system applicable to rotary drilling. It includes a torque meter that measures dynamic torque while drilling. The system averages the time period of individual oscillations in the torque, for a given number of such oscillations. It indicates the length of such average time numerically. Consequently, the probable cause of the oscillations may be inferred.
