PDC Shock Tool
Brand: Challenger Downhole ToolsThis design of our Shock Tool is built with PDC bits in mind. The PDC style bit requires far less weight while drilling, the Challenger PDC style Shock is built to operate and perform better with these lower WOB.
The typical shock is used and designed to operate with Roller Cone style bits that require significantly higher WOB than a PDC, we designed a shock to run with a PDC application which allows the shock to operate better at the lower WOB utilizing its entire stroke more effectively.
When ordering shocks WOB and application information should be considered to assure maximum performance from the Shock Tool.
Features- Reduces drill string vibration and impact from MWD systems
- Adjustable spring rate for P.D.C. applications
- Can be provided in both near bit and string applications
- Does not use temperature-sensitive elastomers for shock absorption, therefore is suitable for use in temperatures to 275°F (135°C), with optional seals available for temperatures up to 450°F (230°C)
- Reliable Belleville disc springs provide optimum load/deflection characteristics to maintain consistent contact between bit and formation, effectively reducing impact loading to extend bit life
- Low friction torsional drive permits free vertical movement
- Reduces wear and tear on rig and equipment, and fatigue failures on drill collars and drill pipe
- Automatically compensates for pump open force
- Isolates bit induced vibrations from the drill string
- Pressure balanced to eliminate the effect of downhole hydrostatic pressure
