Pattern Recognition of Stick-slip Vibration in Combined Signals of DrillString Vibration

•The drill string vibration signals are obtained by the sensors with a three-axis accelerometer and a gyroscope.•Supervised machine learning is used to establish a classification model of vibration patterns.•Through the application of classification model in the actual drill data, the specific vibration types of various modes are clarified, which proves that the model can effectively distinguish different vibration modes and its accuracy can reach up to 95%.
