Our Infinity line of mud motors
integrates the latest generation sealed bearing technology with the
most recent power sections designs.
The ‘Cavare’ bearing housing is a patented innovative straight
and or adjustable bent housing. The unique assembly has 3 radial
supported lubricated bearings that are oil filled with a pressure
compensated oil chamber via efficient flow restriction design. The
output shaft is slightly larger than most other competitor
offerings. This larger diameter increases the strength of the shaft,
reduces the bending stresses and reduces the likelihood of fatigue
induced failures. The single point offset housings are designed with
internal stress relief to provide superior fatigue resistance. This
housing also has an oversized bore allowing easy adjustment on the
rig floor. 13 increments cover a range from 0º to 3º and a shorter
bend allows for better directional performance and control. The
constant velocity connecting shaft has oil filled, sealed universal
joints. Due to the larger I.D through the Adjustable Bent Housing,
larger C.V. joints have been utilized to increasing the strength and
prolonging the life of the shafts.
Our power sections have been carefully chosen from Dyna-Drill® Technologies,
an oilfield supplier of superior products since 1958. Recognized as
technological leaders, their products deliver reliable service in
the most extreme drilling applications worldwide. The power sections
also come with the latest elastomer offering, the NBR-HR™ featuring
improved fluid resistance, superior mechanical properties and
reduced thermal expansion.
Power section sizes range from 2 7/8” through to 11 ½”. Infinity
has also integrated the float valve into the top sub, eliminating an
additional connection.
- The rig must have precise standpipe pressure gauge
and must be capable of pumping the recommended
volume.
- Surface test the motor.
- A drill pipe screen should be run on top of the motor.
- Tag bottom and increase weight until approximately 80% of
the maximum differential pressure.
- If harmonics in the string is created,
manoeuvre the
rotary speed until it becomes normal. We recommend
30-60 RPM for straight-hole applications.
- If motor stalls the pressure will increase. Stop rotation
and throttle back pumps until you reach initial off-bottom pressure and then pick up the
drill string slowly to
release energy stored in the drill string.
- Never lift motor off bottom while under load. Doing so
can cause damage to the motor or can back-off the
connections.
- Never over pump as this can cause damage to the
rotor and stator.
- Non-magnetic drill collars
- Rotary reamers
- Taper blade reamers
- Integral blade stabilizers
- Cross-over subs
