Supply corrector - damper
Own original development protected by patent
Ensure smooth WOB supply and increase nit lifetime
Significant ROP increase and reduction of round trip operations
Preview
Damper is own original “BURINTEKH”, Ltd development protected by patent.
Supply corrector - damper (KPD) is designed for providing optimal uniform loading of rock destruction tool with axial load when drill string movement is carried out nonuniformly by snaps due to friction, as well as for damping axial and torsional loads acting on the bit and BHA during drilling.
Application: Drilling vertical, directional and horizontal wells.
Advantages:
- KPD has straight flow channel and does not create additional pressure drop during operation;
- KPD makes feedback between torque and axial load which allows implementing automatic weight on bit adjustment with simultaneous damping axial and torsional vibrations;
- KPD promotes smooth WOB supply with simultaneous damping axial and torsional vibrations which allows increasing reliability of the whole BHA operation and improve its steerability;
- KPD does not create pressure pulsations while circulation, thus does not reduce the signal quality of the mud pulse MWD.
