The Rock Challenge: Fracturing Rock

摘要

In general rock will vary in some degree on every bore and changes throughout the bore Load and RPM requirements will vary from the start to the end of the bore The most efficient drilling system parameters are 1. those that lead to the largest advancement per revolution 2. those that provide for the fewest number of revolutions in the hole Cuttings Removal Will have a significant effect in drilling operations 1. Poor Cuttings removal will 1.1 increase wear on bit 1.2 lower penetration rate 1.3 generate higher bit temperature - reducing bearing and seal life.
