Relating drilling parameters at the bit-rock interface: theoretical and field studies
An explicit expression relating drilling parameters at the bit-rock contact is derived. The expression estimates the minimum torque, related to bit-rock contact only, required to maintain constant bit rotation. Theoretical results from the developed bit-rock contact relation agree very satisfactorily with those obtained from field tests and other previous experience.
