Optimal bit selection for large-diameter wellbore drilling in an ultra-deep well

Optimal bit selection for large-diameter wellbore drilling in an ultra-deep well

To optimize the bit selection for large-diameter wellbore in the upper section of an ultra-deep well S-1, a full-well dynamic model integrating drill string vibration and bit rock-breaking was established and then verified using measured vibration data of drilling tools and actual rate of penetratio...
