ORIENTED BENT SUB
The oriented bent sub is use for the straight screw drilling tool getting into orientated. The oriented bent sub is a tool use for deflecting of power drilling tools. Under the action of bent sub, a continuous lateral force imposed on the bit, and make the bit continuous side cutting wall of a well, drilled well body carve track. It has the advantages of simple structure, easy to use and low cost.
ORIENTE STRAIGHT SUB
The oriented straight sub mainly cooperates with bend housing motor for directional drilling. Make the clinometers seated in directional bond sleeve, it is used for deflecting, torsional azimuth, side tracking and correction of vertical well in directional well. The oriented bent sub is a major power deflection tool, the power drilling tool exerts a continuous lateral force on the drill bit under the action of oriented bent sub, so that the drill bit continuously cuts the wall of the well laterally and further drill into a curved well trajectory. It has the advantages of simple structure, easy to use, low cost.
