Product Description Product Application HTW series all formation of deep hole drill is a kind of efficient and new type of hydraulic drill, the drill is in our ten years manufacturing and construction experience of drill rig on mining, wells, trenchless, pile holes, core, based on independent research and development, design for complex strata, meet all drilling deep hole in the idea, is the patent drill of alternatives to traditional deep hole roller cone drilling equipment .patent number:201520496371.3 Widely used in shale gas, air conditioning, water well, oil well, mine rescue and other large engineering construction, is domestic first deep hole drilling machine with high efficiency.
Main Features 1.Rig type of optional equipped with high leg for self loading Crawler and truck type, optional diesel engine or motor power.
2.The combined pump transfer case, hydraulic rotary power head, the motor chain propeller, water pump, mud pump parts such as hydraulic configuration, reasonable power matching, speed, pressure regulating block step-less adjustment, achieve a variety of drilling parameters, meet a variety of drilling technology, adapt lo the whole formation drilling requirements.
3.Multiple drilling technology: the soil and sand pebble bed reverse circulation drilling. Moisture rock combination of large diameter DTH hammer drilling composition. All air leakage formation drilling a hole deep casing to follow up. Deep hole water, gas, three complex strata combination DTH hammer drilling mud.

Rigs Detailed DTH hammer and three-wall drilling pipe tech In this technology,the DTH hammer can drill in soil and rock layer for water well and pile hole. In rock, rock weathering, boulder formation, this technology realized 400 - 600 mm diameter and 200m deep water well drilling.
In soil,rock,rock weathering, boulder formation, this technology can realize 3000mm pile hole and 300mm diameter 2000m deep exploratory hole.

Improve drilling efficiency for 3-5 times,save more than half of equipment investment and 40%-60% oil consumption.
For this technology, air supply, air exhausting, and cuttings exhausting are realized separately by three different passages:
when drilling a hole, air supply volume didn’t increase (just keep same like drilling in earth surface) according to the increase of depth, which can reduce equipment investment and oil consumption.?
And exclusive use passage for air exhausting without resistance of cuttings and under waters can improve efficiency of DTH hammer greatly

combined DTH hammer and three-wall drilling pipe. In the middle is a pipe to transmit the air for percussion of DTH hammer.? And the first annular is used to exhaust to the surface for DTH hammer independently. ?The second annular is normal circulation for mud travels to the bottom of the hole.?
