Design and mechanical properties analysis of drill pipe’s joint thread with unequal taper under complex loads

Abstract The design of drill pipe joint thread with unequal taper is proposed to investigate the fracture failure of the API NC38 used in the drill pipe joint of the SU36-8-4H2 well. The effect of changes in thread taper on the stress distribution and mechanical properties of drill pipe joints is an...
