Torque-reducing ridged diamond element cutter block
Improve rock cutting efficiency through a combination of shearing and crushing actions.
Many previous improvements in PDC bit performance were the results of metallurgy and materials changes. That is, until the StingBlade conical diamond element bit was introduced with its unique cone-shaped cutting element. From the success of StingBlade bits, Smith Bits engineers sought to further improve bit performance by developing a new cutter geometry through extensive internal R&D and field testing.
The Axe ridged diamond element features a unique ridge-shaped geometry that combines the shearing action of a conventional PDC cutter with the crushing action of a tungsten carbide insert (TCI). The ridged design of the Axe element enables more efficient cutting and heat dissipation, while also having better frontal impact resistance which is achieved through a thicker diamond layer, proprietary blend of polycrystalline diamond grain-size distribution, and optimized materials.
Wiley Long, Smith Bits Product Champion, discusses how operators are using the Blade Family of bits to reshape their drilling performance.
The unique geometry of the cutting elements features thicker diamond tables to improve impact strength and wear resistance.
Innovative bit with 13-mm Axe elements saves approximately 40 hours of rig time in Yaraktinskoe field.
BHA incorporating bit and reamer with Axe ridged diamond elements lowers torque, improves footage drilled by 14.3% over field median.
Bits with unique-geometry cutting elements increase average ROP 40% through high-impact carbonate formation.
