Drill-string torsional vibration suppression using GA optimized controllers
Publication details: dic. 2009Description: 7 p. ; 32-38 In: Journal of Canadian Petroleum Technology 48Summary: Transcripción del resumen del autor. Failure of drill-strings is very costly in terms of money and time and occurs more frequently than oil companies would like to see. There are many reasons for drill-string failure, such as vibration, fatigue, and buckling. This paper addresses the problem of suppression of stick-slip oscillations in oil well drill-strings using proportional integral derivative (PID) and lead-lag controllers in conjunction with genetic algorithms. Simulation results are presented to validate the proposed control schemes.| Current library | Status | Barcode | |
