Product Details
- Main Structure: High-strength alloy steels such as 42CrMo and 20MnCr5, processed through forging and heat treatment to ensure excellent strength and toughness.
- Cutting Teeth: Tooth heads are made of YG series cemented carbide (e.g., YG11C), with hardness ≥ HRA90 and impact toughness ≥ 12J/cm². Roller cones are reinforced with tungsten carbide for superior wear resistance.
- Wear Resistance Treatment: Key components are overlaid with wear-resistant alloys or nano-coatings to extend service life and reduce replacement frequency.
- Structural Components: Bucket bodies and helical blades use Q345B or high-strength wear-resistant plates, balancing rigidity and lightweight design.
Advantages
Core barrel with Roller-bit – Key Advantages
1. Superior Core Quality & Recovery
Minimal Core Disturbance: The double-tube (or wireline) configuration features a stationary inner tube that remains isolated from the rotating outer barrel. This design protects the extracted core from torsional twisting, bending stresses, and vibrational disturbance-preserving the natural structural integrity of the sample.
Accurate Geological Representation: In fractured, foliated, or weathered hard rock, the roller-bit produces clean, intact core runs with clearly defined bedding planes, fracture orientations, and mineralization zones. This is essential for:
Geotechnical site investigations (dam foundations, tunnels, slopes)
Mineral exploration and resource estimation
Environmental and groundwater studies
Higher Core Recovery Percentage: The gentle crushing action, combined with efficient flushing, minimizes core washout and erosion, delivering core recovery rates consistently above 90–95% in competent hard rock.
2. Efficient Cuttings Removal & Cooling
Optimized Flushing Port Design: Strategically positioned fluid nozzles deliver high-velocity drilling media (water, mud, or air-mist) directly to the cutting face, ensuring:
Instantaneous cuttings evacuation-preventing regrinding, which is a primary cause of premature bit wear
Effective heat dissipation-reducing thermal stress on carbide inserts and roller bearings, thereby extending operational life
Cleaner Borehole: Efficient chip removal keeps the borehole clean and free from debris accumulation, reducing the risk of stuck pipe and improving hole stability-particularly in swelling or reactive formations.
Lower Fluid Consumption: The roller-bit's efficient cutting action requires less hydraulic energy for hole cleaning compared to diamond bits, reducing pumping costs and fluid consumption.
3. Lower Torque & Torsional Stress
Optimized Rolling Action: The rotating roller cones convert high axial load into a rolling/crushing force rather than dragging shear. This significantly reduces the torque required to rotate the drill string, minimizing the risk of rod twist-off or thread fatigue-common failures in deep and deviated boreholes.
Protection for Drill String Components: Reduced torsional vibration extends the service life of drill rods, swivels, and top-drive systems, lowering maintenance costs and improving overall rig safety.
Smoother Operation: The rolling action produces less stick-slip vibration compared to fixed-cutter bits, resulting in smoother, more stable drilling dynamics-a critical advantage when drilling through highly fractured or heterogeneous rock masses.
Production Applications
Mineral Exploration & Mining
The roller-bit core barrel is the industry-preferred tool for hard-rock mineral exploration, where obtaining high-quality, undisturbed core samples is critical for resource estimation and mine planning.
| Specific Application | Why Roller-Bit Excels |
|---|---|
| Gold & Base Metal Exploration | Penetrates quartz-veined host rocks (granite, greenstone, schist) with minimal core loss, preserving visible mineralization and alteration zones for accurate assay correlation. |
| Iron Ore & Hard Hematite | Handles abrasive, high-density iron formations (BIFs) with UCS often exceeding 60MPa, delivering intact runs that accurately reflect grade boundaries. |
| Rare Earth & Hard-Rock Lithium | Effectively cores through pegmatites and spodumene-bearing granites, where conventional bits suffer rapid wear due to high quartz and feldspar content. |
| Deep Exploration Drilling (>500m) | Extended bit life reduces tripping frequency, a critical advantage in deep boreholes where each round-trip can consume 4–8 hours of rig time. |
