Research on Stick-slip Vibration Level Estimation of Drillstring Based on SVM

To evaluate the severity of stick-slip vibration of drill string, a risk assessment method based on factor analysis (FA) and support vector machine (SVM) is proposed. By performing time domain and frequency domain analysis on the simulated torque data, the signal feature values are extracted. The fa...
