特写 Schlumberger Wins 2021 Meritorious Awards for Engineering Innovation
Technologies recognized for excellence and achievement in Drill Bits and Onshore Rigs categories.
StrataBlade
Concave diamond element bit
Impact durability
Thick diamond layer at cutting tip and tapered profile toughens cutter against chipping and breaking
Improved cutting efficiency
Tapered ridge with a thicker diamond table significantly resists impact damage and improves point loading
Increased ROP
Distinctive concave shape decreases effective cutter back-rake angle to cut deeper
Increased cutting efficiency for instant ROP improvement
The StrataBlade concave diamond element bit saves rig time and costs by delivering faster instantaneous ROP. It withstands impact damage in interbedded drilling through medium-strength formations with unconfined compressive strengths (UCS), ranging from 5,000 to 20,000 psi [35 to 140 MPa].

The StrataBlade concave diamond element bit features Strata elements strategically placed along the bit face.
Improved performance in medium-strength, interbedded formations
The strength of the StrataBlade bit is the unique geometry of Strata concave diamond elements. A tapered ridge with a thicker diamond table significantly resists impact damage. And the distinctive concave feature decreases the effective cutter back-rake angle to cut deeper into rock. Combined, these characteristics increase cutting efficiency, delivering up to 35% higher instantaneous ROP with the same input energy. For deep lateral wells where weight transfer to the bit is a challenge, the StrataBlade bit enables better torque response at the bit for superior steerability and conformance to directional trajectories.
