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.A reasonable overall layout uses the tractor-mounted or full ground chassis for transportation with good maneuverability.
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.
A 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, the shallow layer of shale gas, terrestrial heat, etc, and can also be used for coal-mine gas exploitation salvage work.
The top-mounted driving head principal shaft has a great drift diameter, suitable for many kinds of construction work such as slurry drilling, air drilling, and air foam drilling, meeting the demands for well-drilling at different terrain strata.
