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.
a. Keeping bracket is installed on the host to form a double wheel support structure, able to withstand the strong blow
b. Vertical boxes are fixed by four groups of bearings to ensure that the rotary machine has sufficient rigidity to overcome gravel layer and other complex geological conditions.
c. the machine is equipped with national patent technology— a taper clutch, with characteristics of strong transmission torque, easy operation, and free maintenance.
d. 53 x 59 drilling rod adopted, high rigidity and strong delivery torque.
