How to Optimize Drilling Speed Without Damaging Tools

CGE Group Wuxi Drilling Tools CO., LTD. High-precision rope core drilling rods, integrated solution for speed improvement and tool protection

I. Industry Pain Points: Achieving Speed Improvement and Tool Protection is Difficult to Balance

In the mining exploration and deep geological core sampling projects, there has always been a construction contradiction: blindly increasing drilling pressure and raising the rotational speed of the drilling rig to meet the construction schedule can easily cause the drill rod's threads to crack, the rod body to fatigue and fracture, and stuck drill accidents in the hole. Frequent lowering and replacing of drilling tools not only cancel out the time-saving advantage brought by speed improvement but also continuously increase the procurement of consumables, downtime, and labor costs.

To truly achieve cost reduction and efficiency improvement, the core solution must simultaneously achieve two goals: significantly increase the mechanical drilling speed and fully protect the core drilling tools such as the drill rod and drill bit.

CGE GROUP WUXI, with over 60 years of drilling tool research and development experience, uses the DCDMA standard rope core drilling rod as the core hardware, combined with standardized construction processes, completely solves the problem of tool damage during speed improvement in the industry.

II. Core Hardware: Core Quality of CGE Rope Core Drilling Rods, Building a Foundation for In-Depth Speed Improvement

This series of BQ/NQ/HQ/PQ full-size rope core drilling rods are independently produced by the state-owned enterprise CGE GROUP in its own 80,815㎡ modern factory. They use ZT950/40Cr high-strength seamless steel pipes and all production processes are benchmarked against the DCDMA international standard. From material, structure, and process dimensions, they reduce drilling losses and support stable and high-speed drilling:

1. High-precision grinding of inner holes

The inner walls of the rods are treated with precise grinding, which is smooth without burrs, significantly reducing the friction resistance of the rope core assembly during placement and retrieval. Core sampling operations are smooth without stalling, preventing stuck drill bits from slowing down the drilling speed; at the same time, it avoids the rod scraping the rod body and generating metal debris, reducing the wear of the threaded joints from the source.

2. Thickened joints + hardened sealing threads

The joints at both ends of the drill rods are thickened and reinforced, and the threads are formed by precise CNC machining and hardened through heat treatment. The surface hardness of the thread layer is higher, with improved resistance to impact, torsion pressure, and wear. Under the impact load of high-speed rotation and soft-hard alternating strata, it is less likely to experience thread slippage, tooth breakage, or sealing failure; multiple ring-shaped sealing grooves stabilize the mud pump pressure and prevent high-pressure drilling fluid from eroding the thread root, extending the service life of the drill rod joint.

3. Ultra-high toughness ZT950 special pipe material

Selecting ultra-high-strength ZT950 seamless steel pipe as the base material, it has superior tensile, bending, and fatigue resistance compared to ordinary drilling rods on the market. In deep-hole drilling, it can withstand continuous uniform drilling pressure and does not rely on instantaneous impact to break rocks, significantly reducing drilling tool impact losses; the rod body has strong rigidity, with a very small swing amplitude during high-speed rotation, reducing unilateral abrasion and wear of the well wall, and eliminating the failure of rapid drilling due to broken rods.

4. Full-caliber standardized compatibility design

Covering BQ, NQ, HQ, and PQ full series of rope core standard calibers, it can perfectly match mainstream inner pipe assemblies, fishing tools, drill bits, and hydraulic shock auxiliary components on the market. Customers do not need to replace the entire drilling equipment but can only replace the drill rods to implement the non-destructive speed improvement solution, with lower renovation investment and faster implementation.
