High-strength deep hole-specific alloy: Made of high-quality ZT950 steel, with overall quenching and tempering + surface hardening of the joint thread.
The tensile and torsional strength is approximately 40% higher than NQ, suitable for 2500-meter deep hole heavy-duty working conditions.
Strengthened thread design: After hardening treatment, it prevents seizing and is resistant to wear, significantly reducing the risk of deep hole thread sticking.
High coaxiality and rigidity: Full length precise straightening and CNC processing, with coaxiality less than or equal to 0.3 mm/m and straightness less than or equal to 1 mm/m.
The pipe body has a thicker wall and greater rigidity, suppressing the bending of deep hole drilling and improving the stability of the hole wall.
The recovery rate for fractured / weak formations is greater than or equal to95%, meeting the sampling standards for deep exploration.
Adequate inner diameter, allowing the placement of inclinometer and fishing tools, supporting drill while measuring inclination and handling well accidents within the hole.
Reducing the lifting of the drill and the sweeping of the hole, the wear of the threads and drill bits is reduced;
High rigidity add less lifting of the drill, reducing disturbance of the hole wall and the risks of hole collapse and stuck drill;
No need to lift the drill to retrieve the inner pipe core.The efficiency of deep holes of 2000 meters or more is significantly superior to that of conventional drill pipes.

Product Q&A
Q:The models of deep hole drilling equipment and associated drilling tools are diverse. How is the universality of HQ drill rods?
A:
Strictly following the DCDMA international standard, it can perfectly match the entire set of accessories such as HQ drill bits, reaming tools, core sampling assemblies, and fishing tools of the same series. It is compatible with mainstream deep hole core drilling rigs like XY-5 and CSK-1000, and no equipment modification is required.
Q:During construction, operations such as in-cave measurement of inclination, well failure rescue, etc. are needed. Can this drill rod meet the requirements?
A:
The internal diameter is sufficient, and it can directly lower measurement instruments, fishing tools, etc. as auxiliary equipment. It integrates drilling, sampling, in-cave monitoring, and fault handling functions, and is fully functional.
Q:The load of from 1500 meters to 2500 meters is extremely heavy. The strength and torsional resistance of conventional drill rods are insufficient. How should the type be selected?
A:
Specifically designed for deep hole heavy-load conditions, its tensile and torsional strength are superior to those of conventional medium and shallow-hole drill rods. It can stably withstand the load of deep-hole operations within 2500 meters and is the main drill rod for deep mineral resources, geothermal energy, and scientific drilling.
Q:The drill pipe threads are prone to wear, stick, and get stuck, and are replaced frequently, resulting in high usage costs. Has this drill pipe been optimized?
A:
Yes. The rod body and the joint are made of 4130 alloy material. The joint threads are surface hardened for hardening treatment. The hardness difference between the male and female threads forms a reasonable hardness difference, effectively preventing sticking, and resisting wear. Under normal circumstances, the core take rate can reach over 95%, meeting the sampling standards for geological exploration.
Q:Frequent pulling of the drill pipe and sweeping of the hole will aggravate the wear of the drill pipe and drill bit. Can the NQ rope core extraction drill pipe reduce such wear?
A:
Yes. The process significantly reduces the pulling and sweeping operations, reduces the abnormal wear of the drill pipe outer wall, threads, and diamond drill bits, extends the service life of the entire drilling tool set, and reduces long-term operation costs.
