Abstract
Downhole drilling vibration analysis uses angular and linear motion data on a drilling assembly. During drilling operations, pairs of accelerometers measure the angular and linear motion of the drilling assembly. Processing circuitry is operatively coupled to the accelerometer pairs and is configured to determine type and severity of vibrations occurring during drilling based on the angular and linear motion data. Drilling operations can then be modified to overcome or mitigate the detrimental vibrations.
