Effect of Axial Vibration on Sliding Frictional Force between Shale and 45 Steel
Activating drill string vibration is an effective means to mitigate the excessive drag encountered during drilling complex-structure wells. However, the Coulomb model cannot describe the sliding friction behavior between drill string and borehole rock with imposed axial vibrations. To solve this pro...
