DC Drive Drilling Rig/ Jackup Rig 1500-7000m
The drawworks, rotary table and mud pump are driven by DC motors, and the rig can be used in deep well and ultra deep well operation onshore or offshore.
• It can be equipped with top drive device.
• It can be equipped with overall moving slide rail or stepping device to meet the requirements for movement between well locations as cluster drilling is conducted.
