 Adopting
advanced AC-SCR-DC technology, smooth shift changes are available
for drawworks, rotary table and mud pumps for optimum drilling
performance.
Both
swing lift and sling-shot parallel-integrated substructures with 9m
and 10.5m floor and mast are installed on ground and raised
with drawworks power.
Main
brake of drawworks can be hydraulic disc brake or band brake
.Auxiliary brake of drawworks may be air-cooled or water-cooled
electric magnetic eddy brake, or EATON pneumatic disc brake.
Rotary
table is driven by drawworks power through compound drive or by an
independent motor. In addition, emergency device is provided to
drive rotary table via drawworks once in emergency for reliable
drilling operations.
A
separate driller cabin is fitted. Operations for air, electric and
hydraulic, drilling data and parameters are all in the cabin. Logic
control, supervision and maintenance during complete drilling
operations are available by PLC processes. The drilling data can be
stored, printed and remote transmitted. All operations by driller
can be completed in the cabin for better working conditions and less
working strength.
Top
drive drilling system can be equipped.
Integrated skid rail may be provided to meet requirements for
cluster well drilling.
