The drive ways of these kinds of drillingrigs include mechanical drive, electrical drive (VFD or SCR),electro/mechanical drive and others.

    Thecompact skid modular structure is convenient for installation andtransportation. It meets the requirement of entire moving structure and clusterwell drilling. In addition, the drilling rig requires only a small workingspace due to its compact configuration.

    Maststructure types include A type, K type (telescopic vertical hoisting mast,entire hoisting mast), etc.

    Thestructure types of the substructure include swing-up, sling-shot, box-on-box,and telescoping etc.

    Bandbrakes or hydraulic disc brakes can be applied as the main brake; water coolingthrust plate pneumatic brake or FDWS brakes can be used as auxiliary brakes;the energy-consumption brake can be used as the AC variable frequency driverig’s auxiliary brake.

    Thedrilling rigs adopt network and information technology as well as integrateddesign for the control, monitoring and display of power, air and hydraulics soas to realize intelligent and safe control of the driller.

    Astandardization and modularization design and various methods of combining thedesign have been applied in order to increase the universality andexchangeability of the drilling rigs.

    Theconfigurations of the solid control system, well control system, high-pressurepipe manifold system, generator house, pump engine house, doghouse and otherauxiliary facilities can meet the different requirements of the end-users.
