Abstract
According to the principles of rock destruction, mechanical drilling of wells can be carried out in several ways, differing in their physical nature. For medium- and high-strength rock, roller cone bits with milled cutting structure or reinforced with high-strength tungsten carbide pins are used. The roller cone method of drilling implements the principle of bottom-hole destruction due to static impingement of the cutting structure, the rock is destroyed mainly by a piercing, partially blocked chipping. From the energy point of view, such impact on the bottom hole is not optimal.
