Five-Wing Oilfield PDC Bit for Hard Formations (F≤11)
High Wear-Resistant
Stable & Long Life
Hard Formation Specialist
The five-wing oilfield PDC bit is specifically engineered for hard formations with rock firmness coefficient F≤11. Featuring a five-wing symmetrical reinforced structure and oilfield-grade high-wear-resistant PDC cutters, it possesses extremely strong impact resistance and rock breaking capability. Enables stable long-distance drilling in F≤11 hard and highly abrasive formations such as limestone, dolomite, basalt, and granite, significantly reducing bit changes 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 Five-Wing Symmetry
Five-wing symmetrical distribution structure minimizes radial vibration, providing exceptional hole verticality and wall stability. Effectively reduces hole deviation and vibration in F≤11 hard formations, ensuring precision and stability for long-distance drilling.
High Wear-Resistant PDC for Hard Formation Breaking
Utilizes oilfield-grade high-wear-resistant PDC cutters with upgraded diamond layer thickness and bond strength. Provides higher rock breaking efficiency in F≤11 hard rock layers (granite, basalt, etc.) with excellent wear resistance and longer footage per bit.
Strong Impact Resistance for F≤11 Hard Formations
Optimized blade structure and cutter layout effectively buffer impact loads from F≤11 hard formations, significantly reducing PDC cutter breakage and blade fracture risks. Provides better adaptability in limestone, dolomite, and other hard abrasive formations.
Optimized Hydraulics for Efficient Cuttings Removal & Cooling
Large flow nozzles and optimized hydraulic channel 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.
Long Service Life & Reduced Construction Costs
High wear-resistant PDC cutters combined with five-wing even force distribution structure result in lower blade wear rate. Significantly superior service life in F≤11 hard formations compared to three-wing and four-wing PDC bits, with lower cost per meter drilled and 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.
