- Core and Combined Bits
Combined the characteristics of PDC and tricone bits, increases the rate and depth of penetration in complex formation, especially for kick-off section.
Anti-whirl design improves ROP and enhances drilling stability.
Unique gauge with high quality PDC cutter, helps several-fold increasing wear resistance and stability of the bit.
The surface is welded by wear-resistant hard facing material, improves wear resistance and erosion resistance of the bit.
Suitable for complex formation, such as hard formation, interbeds and other compact abrasive formation, etc.
Circular-arc shaped crown design, placed with high quality cutters, significantly enhances drilling footage capability of the bit.
Specially designed core head provides high rates of core recovery.
Optimized waterway design, benefits for the bit cleaning and cooling.
Suitable for coring in soft to medium hard abrasive formation, such as soft shale, limestone, sandstone, etc.
Diamond Core Bits
Short parabolic configuration outer cone crown design, placed high density diamond particles, ensures efficient reaming and drilling while extending the application and performance range of casing running operation.
Provides high rates of core recovery in medium to medium hard abrasive formation, such as limestone, dolomite and sandstone, etc.
Short parabolic configuration outer cone crown design, carefully balances cutting structure that minimizes cutters and casings wear during drilling operation.
Medium density PDC cutting structure design, allows drilling wells with simultaneous wellbore reaming across the interval.
Effectively decreases shirling probability and increases the life of the bit.
Suitable for medium to medium hard formation, interbeds, such as hard shale, limestone, dolomite, etc.
