Drill Rig

Down The Hole (DTH) drill rig capable of drilling to a depth of 300mtrs (1000 ft) under favorable drilling condition. The drill rig can be operated on rocky formation and hard to medium soil formation. The drill rig can make a hole of diameter 4 to 6.

The drilling rigs can fully meet the well-drilling- process requirements by adoption of flexible driving designs- mechanical drives (high-speed diesels, hydraulic transmission box, angle gear box or middle-speed diesel hydraulic transmission, chain combination box), compound transmission and electrical drives (VFD or SCR) etc. * The whole unit is very compact and a quick whole transportation and installation of the whole drilling rig can be realized due to a utilization of a skid-mounted structure. In addition, the drilling rig requires a small working site due to its high integration and compact configuration. * Masts and substructures have various structures, such as: perpendicular-hoist sectional mast, whole-hoist K-type mast, telescopic substructure, spirally hoisted substructure and folding - frame substructure. * A standard and module design and various ways of combination have been adopted in order to boost up the universal and exchangeable performances of the drilling rigs and to meet the user different requirements. * Disc brake or band brake can be applied as main brake and air brake or FDWS brake can be used as auxiliary brake and the energy-consumption braking can be available for electrical-drive-rig auxiliary brake. The drawworks can be equipped with bit-feed motor and control system. * The Internet and communication techniques have been used on the drilling rigs, which can realize an integral display for power, air control, hydraulic control, and monitoring and the intellectual and safe control of the driller. * The perfect configurations of the solid control system, well control system, high-pressure pipe manifold system, the generator house, the engine pump house, doghouse and other auxiliary facilities can meet the user different requirements. Safety and inspection measures are strengthened under the guidance of the design concept of ° Humanism Above All¡± to meet the requirements of HSE.

1.High drill head lifting force; 2.Suit to various drill tools; 3.High hoist lifting force; 4.High drill efficiency; 5.Adaptable to various strata; 6.Rinse medium can use both mud and air. As per customers' requiremnt

The draw works is driven by two VFD AC motors with 1+1r/2+2r step-less speed, and reversal will be realized by ac motor reversal. The mud pump is driven by VFD AC motors, which are mounted on the rear skid of mud pump, with v-belt transmission and simple structure. The independent driven rotary table runs with 1+1r/2+2r step-less speed, and reversal will be realized by ac motor reversal. Using AC-DC-AC drive technology, rotary table and draw works are four quadrant running and full digital vector control. Single drum, gear driven and one / two shifts smooth speed change draw works is simple in structure and reliable in operation. Feed back / dynamic brake is adopted to replace eddy current brake as auxiliary brake. Automatic drilling is obtained by draw works main motor or an independent motor. Intellectual position control for traveling block prevents crown block and rotary table from collision. Real time communication and network is available by using profibus technology. K type mast is suitable for install top drive system. Sling shot or swing up substructure and mast are applied so that all the equipment can be installed at lower position. Suit for any transportation.
