Directional Through-cable Drill Pipe

Material of Drill Pipe

Product Features

Main Technical Parameters

The directional through-cable drill pipe adopts S135 petroleum grade

geological pipe, which adopts integral quenching and tempering heat treatment

and has high strength and toughness

It is mainly used for supporting directional drilling rig in deep-hole directional

drilling, and it is one of the main drilling tools for directional drilling construction

of underground tunnel in coal mines. The special customization of the thread

structure of the drill pipe ensures reliability and tightness, and bending without

tripping in complex terrain ensures reliable signal transmission during drilling.

Large-diameter Grooved Spiral Drill Pipe

Material of Drill Pipe

Product Features

Main Technical Parameters

The drill pipe body is made of thick-walled high-quality alloy steel pipes, and

the threaded joints at both ends are made of high-strength alloy steel to have

the characteristics of high strength and good toughness.

The large-diameter grooved spiral drill pipe is mainly used in

the drilling construction of easy-to-collapse holes in soft coal

seams. After the hole is formed with the large-diameter grooved

spiral drill pipe, the screen pipe can be directly inserted into the

inner hole of the drill pipe without withdrawing the drill bit, so as

to complete the process of screen pipe lowering and improve

the drilling construction efficiency.

Highlights

Technical indicators Adaptive hardness coefficient (general type) Adaptive hardness coefficient (reinforced type)

The diameter gradually decreases from bottom to top to have

good anti-deviation effect during drilling. The small drill bit is used

for positioning and hole opening, while the large drill bit is used

for drilling and hole expanding, which reduces the weight on drill

bit during drilling, has long service life, and is not easy to deviate

during drilling.

Openable/closeable Diamond Composite Drill Bit

Highlights

Main Technical Parameters

The openable/closeable diamond composite drill bit matches

the large-diameter grooved spiral drill pipe, and is one of the

important components of the complete set of drilling tools for

screen pipe lowering. The screen pipe can pass through the

drill bit center. The center blade of the openable/closeable

drill bit adopts hinged structure and is equipped with spring

pin shaft for positioning. The center blade can be opened and

closed flexibly, reused and is suitable for construction in

various strata.
