The drilling rig uses the AC frequency converting technique to realize the stepless variable drive and the modularized design, further speeding up the moving and reducing the truck number.
The drilling rig has a parallelogram substructure and a telescoping mast. The mast is raised by cylinders and expanded or contracted with wireline, 1 500kW AC frequency converting motor is used to drive the drum shaft of the drawworks through the counter shaft and the roller chain. The drawworks has two gear shifts---high speed and low speed. The gear shifting is made by using the push-disc type clutch. The main brake is the hydraulic disc brake. The rotary table is connected to the drawworks with the chain and driven by the drawworks. The closed chain compound case uses the fully forced splash lubrication. The auxiliary brake is FDWS-15 air-cooling electromagnetic eddy current brake.
All the drives are mounted on the substructure that, as a rig platform, is equipped with setback area, rotary beam, rotary table, disc brake and mechanized wellhead tools.
In addition, the drilling rig is equipped with F-1000 mud pump, 800kW diesel generator set, frequency converting control system, solids control system and doghouse.
