HFX series deep (water) well drilling rig uses full hydraulic control, and the Top drive to drive the rotation of drilling tools with very high drilling efficiency. Reasonable overall layout uses the tractor-mounted or full ground chassis for transportation with good maneuverability. Very flexible in difficult roads and can be widely used in many fields such as resource exploration of hydrology wells, coal bed methane, shallow layer of shale gas, terrestrial heat, etc, and can also be used for coal-mine gas exploitation or salvage work.
