Six-Wing Oilfield PDC Bit for Hard Formations (F≤11)
Superior Impact Resistance
High Wear-Resistant
Exclusive for Hard Formations
The six-wing oilfield PDC bit is specifically engineered for hard and highly abrasive formations with rock firmness coefficient F≤11. Featuring a six-wing symmetrical reinforced structure and oilfield-grade high-wear-resistant PDC cutters, it further improves force distribution uniformity and impact resistance compared to five-wing bits. Enables more stable, longer-distance drilling in F≤11 hard formations such as limestone, dolomite, basalt, and granite, significantly reducing bit change frequency and construction costs. Suitable for water wells, geothermal, mining, and other engineering requirements.
Extensively used in water well drilling, shallow geothermal development, mining drilling, and hard formation engineering exploration.
Core Advantages
Ultimate Drilling Stability with Six-Wing Symmetry
Six-wing uniform symmetrical distribution structure minimizes radial vibration and movement, providing exceptional hole verticality, roundness, and wall smoothness far exceeding three/four/five-wing bits. Effectively reduces hole deviation in F≤11 hard formation long-distance drilling, ensuring hole accuracy and construction continuity.
High Wear-Resistant PDC for Efficient Hard Formation Breaking
Utilizes oilfield-grade high-wear-resistant PDC cutters with upgraded diamond layer thickness and bond strength. Provides higher shear rock breaking efficiency in F≤11 hard rock layers (granite, basalt, etc.) with excellent wear resistance. Footage per bit further improved compared to five-wing bits.
Superior Impact Resistance for F≤11 Hard Formations
Six-wing structure distributes cutting loads more evenly with optimized blade and cutter layout, effectively buffering impact loads from F≤11 hard formations. Significantly reduces PDC cutter breakage and blade fracture risks, providing better adaptability in highly abrasive hard formations.
Optimized Hydraulics for Efficient Cuttings Removal & Cooling
Large flow nozzles and multi-channel hydraulic design ensure sufficient cooling of the bit and efficient cuttings removal by circulating fluid, reducing cuttings accumulation and bit overheating wear, improving continuity and efficiency in F≤11 hard formation drilling.
Ultra-Long Service Life & Reduced Construction Costs
High wear-resistant PDC cutters combined with six-wing even force distribution structure result in lower and more uniform blade wear rate. Significantly superior service life in F≤11 hard formations compared to three/four/five-wing PDC bits, with lower cost per meter drilled and substantially reduced downtime for bit changes.
Applications
Suitable Formations
Limestone, dolomite, basalt, granite, and other hard and highly abrasive formations with rock firmness coefficient F≤11.
Note: Specifically designed for F≤11 hard formations.
Not suitable for ultra-hard formations with F>11 or soft to medium soft homogeneous formations.
Drilling Method
Rotary Drilling – Recommended to use with mud circulation or high-pressure water circulation for efficient bit cooling and cuttings removal, further extending bit life and improving rock breaking efficiency.
