Balance technology for specific applications

摘要

Ranking the relative importance of key performance indices in specific applications enables optimal technologies to be applied to improve drilling performance. Years of research and experience show that optimal bit selection results from careful consideration of the four fundamental, interdependent indices that describe bit performance: Rate of penetration (ROP) - how fast the bit will drill for a given weight on bit; Stability - how resistant the bit is to lateral vibration; Durability - how resistant the bit is to abrasive wear; and Steerability - how the bit responds to side forces and therefore how steerable it is on rotary steerable systems.
