Description
BQ wire - line drill pipe is a core tool for wire - line coring drilling in geological exploration. It is used to connect the drilling rig and the diamond bit, transmit torque and drilling pressure, and provide a passage for the inner tube assembly. Benchmarked against mainstream global products, the drill pipe body has a specification of 55.6×4.8mm, suitable for medium - deep hole drilling within 1300m. It is widely used in geological exploration, engineering geological survey, deep - mine drilling, mineral exploration, etc.
Drill rod pipe: Made of high - strength ZT950 seamless steel pipe, with overall quenching and tempering treatment. The straightness is ≤1mm/m, featuring high coaxiality, strong bending and torsion resistance.
Threads: The threads are quenched and tempered, with anti - galling, wear - resistant properties, and easy make - up and break - out.
Joint: It has a self - connecting integral structure without welding, boasting high strength and good stability.
Supporting Tools: BQ diamond bit, inner tube assembly, fishing tool, winch liner, swivel, etc.

Product Features
The tensile strength of the drill rod is very high. torque during the drilling process is low.Increased wear resistance, the hardness of the thread increases to above HRC55, which can enhance the wear resistance and anti-sticking ability. the rod body undergoes high-frequency treatment to improve the wear resistance; the QA series drill rod adds the high-frequency quenching process increasing the wear resistance of the rod body by 50%.
Application scenarios
Mineral exploration: Exploration and detailed investigation of non-ferrous metals / precious metals such as gold, copper, and uranium.
Geological survey: Regional geological mapping, structural exploration, core sampling of fault fracture zones.
Engineering drilling: Preliminary investigation of foundation for high-rise buildings, dams, and tunnels.
Water wells / geothermal: Water extraction from shallow to medium-deep wells, geothermal exploration holes (≤ 1300 m).
Core Competitiveness & Product Advantages
Efficient core extraction: Without core drilling, the number of trips up and down the well is significantly reduced, and the efficiency is increased by 2-3 times.
Complete core: The inner tube provides protection, with a core extraction rate of ≥ 95%, and the structure is not disturbed.
Heavy-duty and durable: Quenching + thread hardening, resistant to torsion, compression, and wear, suitable for complex formations.
Suitable for deep holes: The deeper the hole, the more significant the efficiency advantage. The cost-effectiveness is the highest within 1000 meters.
Cost reduction and efficiency improvement: Reduces labor and equipment losses, and the overall cost is reduced by 30% or more.
FAQ
Q1: Conventional drill rods require frequent tripping, which leads to low working efficiency. How to solve it?
A: BQ wireline core drill rod allows core recovery without pulling out the whole drill string. We only need to retrieve the inner tube assembly inside the rod, which greatly cuts auxiliary time and improves overall working efficiency.
Q2: Frequent assembling and disassembling drill rods cause high labor intensity and labor costs.
A: It reduces repeated rod handling work, lowers workers’ labor intensity, and effectively saves labor costs, ideal for long-term field drilling projects.
Q3: Ordinary rods are easy to twist, crack or deform in shallow to medium-deep holes within 1300m.
A: Made of ZT950 material, this drill rod features excellent torsion resistance, compression resistance and fatigue resistance. With size 55.6mm × 4.8mm, it works stably and is not easy to damage within 1300 meters depth.
Q4: Threads of common drill rods wear out and gall easily, resulting in frequent replacement and extra costs.
A: Manufactured in accordance with DCDMA standards, the connecting threads are wear-resistant and anti-galling. Longer service life reduces replacement frequency and lowers operating costs.
Q5: Tripping operations often disturb core samples and lead to low core recovery rate.
A: The inner tube assembly holds core samples while the drill string stays in place. It prevents core breakage and disturbance, ensuring high core recovery rate for geological and mineral testing.
