Drilling rig, a complex set of machines, which consists of machines, units and mechanisms. Drilling rig is in the exploration or mineral resources (combined solid ore, liquid ore, gas ore, etc.) development, drive the drilling tool into the underground Drill into the ground to obtain physical geological information of mechanical equipment. It is also called drilling machine. The main function is to drive the drilling tool to break the rocks at the bottom of the hole and to lower or raise the drilling tool in the hole. It can be used to drill cores, mineral cores, rock chips, gaseous samples, liquid samples, etc. Rock chip, gas sample, liquid sample, etc., in order to explore the underground geology and mineral resources and other conditions.

2. Desert drilling rigs
4. Continuous pipe rigs
5. Inclined well drilling rigs
