The descriptions of the deep borehole drilling DTH crawler mounted well drilling rig.
The deep borehole drilling TDH crawler mounted well drilling rig is a type of drilling equipment that is designed to drill a deep water well borehole through the DTH drilling method, it is a type of compressed air drilling method, and the compressed air goes through the DTH hammer and the DTH hammer will produce the hitting movement, that hits the rocks into pieces. The deep borehole drilling DTH crawler mounted well drilling rig can drill 300m in depth, and the water borehole diameter will be from 140mm to 325mm. The recommended drilling pipe for this DTH crawler well drilling rig is Φ76mm, Φ89mm, and Φ102mm.
