An innovative and cost reducing solution to today's drilling requirement's: The Dynomax Regulator
March 21, 2016
Today’s drilling applications are becoming more challenging with deeper, longer and more complex wells being drilled faster than ever before. One challenge is keeping the hole clean while drilling, which is achieved with higher flow rates. These flow rates are limited by the power sections on the motors and quite often lead to premature failure due to over-pumping.
The Regulator employs a variable size exit orifice to actively moderate the flow that goes through the motor continuously – extra fluid is vented out the side. The exit orifice is controlled by a valve that measures the flow entering the motor. The valve mechanism responds in milliseconds so that flow to the motor is always regulated.
Utilizing the Regulator sub allows the preservation of the hydraulic power of your motor through all drilling conditions. With the Regulator sub you always get the optimum rate of flow through the power section, just like normal drilling without a ported rotor or similar device (a common method of bypassed additional flow for hole cleaning purposes when the motor is the limiting factor). Now you can pump as much as you want without damaging the motor or interrupting drilling in order to drop a ball or other mechanical "signaling" device. As well, with the Regulator sub, your differential pressure remains a reliable way of determining weight on bit and motor torque load; you can see stall events as you are used to seeing them.
- Reduce stator failures due to over pumping
- Utilize optimal performance of the power section in motors
- Reduce washing out of components in the motor
- No need to drop balls or darts for activation
- Motor stalls are still visible at surface
The Regulator is perfect for the following applications:
- Conventional Drilling
- Coil Tubing Applications
- Prevent Over-Pumping the Motor
- Better Hole Cleaning
The Regulator is currently available in sizes ranging from 2 7/8” OD through 6.5” OD.
