Advantages of a Drilex Multi-Lobe Power Section

Below are a few advantages the Drilex power section has over other power section on the market today:

• Broader Flow Rate Ranges
   
• Provides fine tuning of annular velocities and better hole cleaning capability.
   
• Allows the optimization of bit hydraulics, particularly with respect to the high hydraulic horsepower required at the bit face of modern polycrystalline diamond compact (PDC) bits.
   
• Increased Output Power and Torque
   
• Generates higher differential pressures
   
• Allows for increased weight on bit (WOB)
   
• Reduces stalling with aggressive PDC bits.
   
• Provides the torque required to drill with larger assemblies below the motor such as
  under-reamers, large diameter bits, hole openers, and core barrels.
   
• More available torque to overcome lateral and offset stabilization.
   
• Optimized Rotor / Stator Design
   
• Rotational speed is approximately proportional to flow rate.
   
• Output torque is proportional to differential pressure at a constant flow rate.
   
• Higher multi-lobe configuration greatly reduces the eccentric motion of the rotor resulting in smoother running power sections.  This helps to reduce vibration with can result in interference with measurement-while-drilling (MWD) signal transmission.
   
• Precision profile manufacturing requiring no post-machine sanding or polishing.
   
• Shorter overall lengths allow more rapid build rate angles in directional applications.
