Small Water Well Drilling Rig 300 Meter China Mobile Well Drilling Rigs Machine Price
Product Description
deep(water) well drlling 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 all terrain chassis for transportation with good
maneuverability. Very flexible in difficult roads, it can be widely
used in many fields such as resource exploration of hydrology
wells, coalbed methane, shallow layer of shale gas, terrestrial
heat, etc, and can also be used for coal-mine gas exploitation or
salvage work.
The top-mounted driving head principal shaft has a great drift
diameter,which is suitable for many kinds of construction work such
as slurry drilling, air drilling, and air foam drilling, meeting
the demands of well-drilling in different terrain strata.
* Mature and reliable hydraulic top drive power head with large
bearing capacity and good sealing effect.
* The gap adjustable telescopic drill collar can meet the requirements of long casing construction and has high work eficiency.
* Unique hydraulic matching technology for high system efficiency.
* Integrated visualization pressurize and pressurize decompression feed system for fine adjustment of diling pressure according to dilling depth.
* Four hydraulic high supporting legs are provided to achieve rapid leveling of the rig without liting. The swing-type centering device provides a wide working space when working.
