Fixed Angle and Variable Angle Oriented Bent Sub for Horizontal Directional Well
The oriented bent sub is a special deflecting joint. It is divided into fixed angle bent sub and variable bent sub. The oriented bent sub is a major power deflection tool having a fixed angle (α) deviated from low end thread of the bent sub to axial line of drill stem. The power drilling tools under the application of oriented bent sub give the bit a constant lateral force to ensure that the bit can cut on the well-wall laterally and further drill into a curved well trace. It is simple in structure, easy to use, and low cost.
