Regulators
Brand: Dynomax Drilling Tools IncToday’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 Patented RegulatorTM 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 begins responding in milliseconds so that flow to the motor is always regulated.
Features- 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
- Applicable not only conventional drilling, but also coil tubing, and completion operations
