Product Description
HFW-200A all formation water well drilling rig 200m

Production Description:

HFW - 200A series of the all formation water well drilling rig is a kind of efficient and new type of hydraulic drill, the drill is in our ten years mines, wells, trenchless, pile holes, core drill based on the working experience in manufacturing and construction of independent research and development, in view of the complex formation design, satisfy the formation drilling, is replace the current single small aperture of rock drill, reverse circulation drill, normal circulation drill patent product.patent number:201520496371.3,widely used in all strata drilling pile sinking wells, small hole construction. Also can be applied to the mine rescue drill, large mining blasting hole construction, is a domestic initiative, the construction technological is the strongest comprehensive water well drilling rig.

1.Innovation technical,patent combined DTH hammer and three-wall drilling pipe

Three-wall drilling pipe is adopted in this technology. 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. And the mud travels back to the surface around the outside of the drill pipe. This is combined the normal circulations of air and mud drilling technology for small diameter (below 300mm). It's also adopted three-wall drilling pipe, and cluster type combined DTH hammer. In the middle is the pipe for water reverse circulation to up the cuttings. The first annular is air-power for DTH hammer for percussion and the second annular is for exhausting of DTH.This technology is used for deep (200m) big diameter (400mm-3000mm) hole.

2.Fill the blanks of large diameter and deep depth water well, pile hole in rock layer

(1) Traditional water reverse circulation drilling technology is only suitable for soil layer
(2) Traditional mud normal circulation drilling technology is widely used for mud rock, limestone and strong weathered rock with slow drilling speed (for example a well with 300mm diameter,400m depth usually takes 6-12 month) and it's not suitable for rock layer and weakly weather rock.
(3) Traditional DTH hammer of air normal and reverse circulation drilling technology is used for rock layer and weakly weathered rock with high e
quipment investment and oil consumption (for example if a well with m
ore than 400 in diameter at the depth of 200m, 2-3 air compressors are needed)
(4) HANFA "air be only for percussion purpose and no deslagging" technology
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 technologycan drill 400 - 600 mm diameter 200m deep water well.In soil,rock,rock weathering, boulder formation, this technology can realize 3000mm pile hole and 300mm diameter 2000m deep exploratory hole.

3.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.

Main Feature:

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 stepless 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.

4.Patent method:

rock hole diameter of 600 mm, moisture combination of DTH hammer drilling, save 50% use air compressor, improve the efficiency of 20%.

300 mm diameter drill 800 m deep water, gas, DTH hammer drilling mud three medium combinations, alternative roller rock drilling, improve the speed by 200%

5.High pressure mud pump, positive and negative circulation pumps, drilling frame lift ing, drilling platform opening and closing, the drill pipe discharge, leveling, winding, drill leg walk all with auxiliary motion of the controlled by hydraulic, such as improving construction efficiency. Reduce the intensity of the operator work.

6.Hydraulic system equipped with separate air-cooled hydraulic oil cooler,and can optional install water cooler to ensure hydraulic system keep continuous and efficient operation under the high-temperature weather conditions of different regions.
