Introduction of spiral twist drill rod:
Drill rod for coal mine is a steel pipe with threads at the tail, which is mainly used to connect the surface equipment of the drilling rig with the drilling and grinding equipment or bottom hole device at the bottom of the drilling well. The main function of drill rod for coal mined is to transport drilling mud to the drill bit and lift, lower or rotate the bottom hole device together with the drill bit. Drill rod for coal mine can withstand huge internal and external pressure, twisting, bending and vibration, so we need to use high-strength materials to manufacture drill rods, and undergo heat treatment and quality inspection.
Features of spiral twist drill rod:
1. High speed spiral drill rod can adapt to a variety of well exploration environments.
2. High speed spiral drill rod has good bending, torsion and impact resistance.
3. High speed spiral drill rod can ensure drilling accuracy, reduce deflection and wear.
4. High speed spiral drill rod optimizes the weight of drill rod while ensuring strength, improves drilling rig operation efficiency and reduces energy consumption.
The role of spiral twist drill rod:
1. In core drilling, spiral twist drill rod can be used for geological surveys and mineral exploration (such as gold, iron, copper, etc.).
2. In open-pit/underground mining, high speed spiral drill rod can be used for drilling in blasting holes and anchor hole construction.
3. In oil and gas exploration, oil drill rods and natural gas drill rods are used for deep drilling.
4. In coalbed methane development, spiral twist drill rods are used for high-strength drill rods used in directional drilling.
5. In hydrological monitoring wells, spiral twist drill rods are used to install groundwater monitoring equipment.
The types of drill rod:
1. Six-sided triangular grooved drill rod: solves the problem of deep hole drilling in high-gas soft coal seams and avoids the accumulation and blockage of coal powder in the borehole; at the same time, the discontinuous spiral grooves on the surface can assist the transportation of coal slag to the outside. When the hole collapses in the hole, the spiral grooves can be used to transport the collapsed hole out, so it is not easy to suck the drill or get stuck.
2. φ89X3000 cable grooved drill rod: a drill rod specially designed for directional drilling in coal mines, mainly used for near-horizontal long-distance gas extraction drilling and water exploration drilling construction in coal mines, and can also be used for directional drilling construction such as near-horizontal engineering drilling on the ground and tunnels. It has the characteristics of long service life, good anti-sticking performance, high transmission efficiency, carrying efficiency and stability.
