The oriented straight sub mainly cooperates with bend housing motor for directional drilling.Make the clinometer 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.
