Power increases, and reaming track is deviateed with guide track and unfreezing.
Horizontal orientation returns counterboring construction as provided power using helicoid hydraulic motor, and with common drill assembly, i.e. drilling rod is direct
Borehole-enlarging drilling tool is pulled to carry out back dragging construction, if using the drill assembly of helicoid hydraulic motor+drill bit, because helicoid hydraulic motor can provide enough
Torque and higher rotating speed, the card resistance in bit operation can be reduced and ensure that drill bit works at higher rotational speeds, improve
Machine speed.If conventional screw drilling tool is applied returns counterboring in horizontal orientation, drilling tool can bear great pulling capacity during construction, close
String bearing at spindle nose cannot effectively operate even fragmentation card resistance, transmission shaft upper end and power section connection screw thread since pressure-bearing is excessive
Also the major accidents such as spindle nose is threaded off or even spindle nose is broken can be caused to occur by larger axial tension.Therefore conventional screw drilling tool is not
Expand demand suitable for the brill of heavy caliber, long range and changeable geology, reaming efficiency is low, and safety accident easily occurs, it is difficult to meet water
The needs such as the torque of flat Directional Drilling power reaming and tension.
