Optimized rotation of drilling string during the Sliding Mode, the Directional Drilling

摘要

An exemplary method of optimizing the rotation of a drilling machine that combines the drilling machine with the drilling hole and places it in the drilling hole can determine the angular velocity of at least part of the drilling machine, and can also determine a critical angular velocity to avoid friction. Static electricity. In addition, a minimum input torque can be determined to suit the drilling platform, keeping the angular velocity at or above the critical angular velocity. The method also includes generating control signals for more than one driving engine, at least partially depending on the engine,Bend at the smallest two inputs.
