The diverter wedge is used to change the direction of the drill string. It creates the required tilt angle, which allows drilling wells at an angle or horizontally, which is often required to develop oil or gas deposits located in certain geologic strata.
Deviation angle control:
Using the deflector wedge, the drill string can be deflected by a predetermined angle to reach the desired well point, which is important for drilling accuracy.
Drilling accuracy:
The deflector wedge helps maintain the accuracy of the deviation of the borehole, reducing drilling errors and ensuring the correct direction to the target zone.
Minimizing geologic challenges:
In challenging geologic conditions (such as when drilling through high-density or low-permeability areas), the diverter wedge helps guide the drill string accurately and avoid potential problems such as tool jamming or misdirection of the hole.
Advantages of using a diverter wedge (DWB):
Drilling flexibility: Ability to drill both vertical, deviated or horizontal wells, which is important for different types of fields.
Improved accuracy: Ensures that the well is accurately deviated to a specified angle for efficient field development.
Risk Reduction: Reduces drilling errors and helps avoid problems associated with misdirection of the well.
Efficiency: The deviation wedge allows drilling along complex trajectories for more efficient field development.
