Friction Reduction and Buckling Behavior of a Horizontal Drill String Under Axial Vibration
Severe drill-string–wellbore friction during slide drilling limits axial-load transfer and reduces drilling efficiency in extended-reach horizontal wells. To investigate the mechanical response of a horizontal drill string under axial vibration, a three-dimensional geometrically nonlinear finite element model was devel...
