Description

Downhole Shock Sub effectively reduces impact loading on the bit toextend bit life and reduce bit trips.  By isolating axial bit vibrations from the drill string.

the shock Sub will reduce lateral and Torsional drill string vibrations, and related fatigue damage or failure of the rotary connections.

The shock Sub allows optimum bit speedto be used under rough drilling conditions, increasing the rate of penetration.

 

Features / Benefits

• Does not use temperature-sensitive elastomers for shock absorption, therefore is suitable for use in temperatures to 250°F (120°C), with optional seals available for temperatures up to 320°F (160°C).
• Reliable Belleville disc springs provide optimum load/deflection characteristics to Mantain consisten contact between bit and formation,effectively reducing loading to extend bit life.
  
• Isolates bit induced vibrations from the drill string.
  
• Fully oil-sealed and lubricated for extended service life.
  
• Pressure balanced to eliminate the effect of downhole hydrostatic pressure.
• Low friction Torsional drive permits free vertical movement.
  
• Well-stabilized, with internal three-point lateral support to minimize deflection.
  
• Reduces wear and tear on rig and equipment, and fatigue failures on drill collars and drill pipe.
  
• Automatically compensates for pump open force.
