Abstract:
1. A drilling assembly in a drill string for drilling an earth formation, said drilling assembly being operable for applying a substantially continuous force on a drill bit during drilling operations to thereby maintain said drill bit in contact with said earth formation, said drilling assembly being threadably connectable utilizing a drilling rig, said drilling assembly comprising: a first outer tubular; a first threaded connector secured with respect to said first outer tubular; a first threaded connector force transfer member mounted for axial movement within, said first threaded connector, said first threaded connector force transfer member being operable for transmitting at least a portion of said substantially continuous force through said first threaded connector; a second outer tubular; a second threaded connector secured with respect to said second outer tabular; and a second threaded connector force transfer member mounted for axial movement within said second threaded connector, said first threaded connector and said second threaded connector being threadably connectable utilizing said drilling rig, and after said first threaded connector and said second threaded connector are connected utilizing said drilling rig, then said second force transfer member is mechanically interconnected with said first force transfer member for receiving said at least a portion of said substantially continuous force.
