    摘要: A drilling accelerator that is driven from a rotational drive to generate a percussive axial motion on a drill bit. The drilling accelerator includes a drive connection to mechanically convert rotational drive to axially directed percussive motion. A wellbore tubular connection is also disclosed that transitions torque to resist back off when left hand or right hand torque is applied.
