There are two types: the skid-mounted CBM drilling rig and the truck-mounted CBM drilling rig. A 9842ft drill depth is designed for the skid-mounted type and 2296ft-9842ft drill depth is designed for the truck-mounted type respectively. The truck-mounted CBM drilling rig has mechanical drive and hydraulic drive, whose power unit, mast, drawworks, rotary table (power end), and air compressor are all installed on the truck to create good moving capability. Hoisting operations and rotary operations of the drilling rig are controlled by a hydraulic system.
The CBM drilling rig can meet the requirements of mud drilling, air drilling, clean water drilling, foam drilling and the other types of drilling as well.
