New-generation shaped cutter elements expand capabilities of PDC bits to boost ROP, efficiency

摘要

SINCE IT WAS INTRODUCED TO THE oilfield more than 40 years ago, the poly-crystalline diamond compact (PDC) bit has emerged as one of the most significant step-changes in drilling tool technology. Continuing advances in the material properties and manufacturing processes used to fabricate the cutting structures of the bit have enabled the industry to tap into formations once deemed drillable only with roller cone bits, simultaneously improving average rates of penetration (ROP) by 60%.
