Review on Stick-slip Vibration's Mechanism Analysis and Its Control Strategy in Deep Drilling with Drag Bits

Abstract

The stick-slip Vibration is one of the major causes for drilling quality reduction, shorter drilling tool lifespan, drilling efficiency decrease, it also affect the drilling cost and completion period seriously. The complex situations in the process of drilling result in the slow progress in this aspect, they rarely break through. The recent advances are outlined in stick-slip vibration of the drill string in three areas: theoretical analysis, experiment research and control strategy. The main research direction, methods and existing problem in the progress are introduced, which will provide reference and guidance for further research.
