DC Electric Drilling Rig
1. ZJ40~ZJ70 RIG
2.conform to the API specification
3.Adopting advanced AC-SCR-DC technology
DC Electric Drilling Rig Technical characteristics*Adopting advanced AC-SCR-DC technology;*Both swing lift and sling-shot parallel-integrated substructures with 9m and 10.5m floor height are optional. All parts on rig floor and mast are installed on ground and raised with drawworks power;*Main brake of drawworks can be hydraulic disc brake or band 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 one in emergency for reliable drilling operations;*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.
