Perspective solutions for the design of drilling tools

Abstract

The article considers the ways to solve optimization problems of drill bits on a deterministic basis through studying and using the "Regularity of energy consumption of dynamic systems from resistance to motion forces", which directly indicates the causes of bit balling formation, the reasons for the insufficient stability of the bearing assemblies of the cones, the causes of instability of the drill bits at the bottom of the well. Theoretical grounded search was done to use certain methods for designing drill bits of cutting-abrasive type, working in the rotational steam mode, which determine uniform wear of armaments for all crowns of working matrices and uniform destruction of the rock through all of the annular bottom hole.
