Navi-Drill Mach 1/AD
The Navi-Drill Mach 1/AD motor is designed specifically for use in holes
drilled with air and mist. With an AKO, the steerable motor drilling system
combines directional and straight hole drilling capabilities to provide
precise directional control. Generally, in one run it can establish the desired
direction and inclination for the surface interval of a directional well.
The AKO places the bend close to the bit, and can be adjusted so the motor
housing tilt angle can be configured on the rig floor to settings from 0° -
2.5°. The resulting dogleg capability can be as high as 12°/100 ft. The
unique AKO design requires no shims to adjust the bent housing angle, so a
single motor can achieve a variety of build rates.
This motor, with the AKO, can perform directional work when oriented in
a particular direction, and is capable of drilling straight ahead when the
drillstring is rotating. This is accomplished by tilting the bit relative to the
motor and/or applying a side force at the bit while maintaining a minimum
amount of bit offset relative to the axis of the motor.
When an alignment bent sub (ABS) is fitted to the top of the motor and
used in conjunction with the AKO, the motor configuration can be used for
building angle, as in a fixed angle build motor. Orientation of the motor
and drillstring is possible in this configuration, but not rotation. The
maximum build rate possible from this configuration is approximately 20°/
100 ft.
