摘要
Downhole drilling vibration analysis uses angular and linear motiondata on a drilling assembly. During drilling operations, pairs ofaccelerometersmeasure the angular and linear motion of the drilling assembly. Processingcircuitryis operatively coupled to the accelerometer pairs and is configured todeterminetype and severity of vibrations occurring during drilling based on the angularandlinear motion data. Drilling operations can then be modified to overcome ormitigatethe detrimental vibrations.
