Description of the DC Electric Drilling Rig
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.
