| Abstract: | The connection of drilling stem is a major disabled part,and the connection screw thread is the chiefly factor of the connection stress distributing.Making use of finite soft ANSYS to analyses and compare the three major shape of screw thread including double-shouldered,pitch and screw model,this will afford important reference for kilometer-rig drilling stem. |
