Energy Model of Ground Cutting Well Drilling

It is proposed that the length of the crack that occurs during brittle fracture of materials be used to calculate the frequency of bit rotation. An adequate cutting angle of the tool is used to create tensile stresses in the soil mass during drilling. The thickness of the soil chips cut off in one revolution, i.e. specific feed, and the frequency of rotation of the tool are calculated based on the critical length of the crack in the tensile volume of the soil. Cutting the soil with the right cutting angle and bit rotation speed consumes the least amount of energy. The developed approach for determining the soil loading frequency eliminates the need to calculate the oil recovery factor while drilling wells, and it is the first estimate in justifying tool rotation frequency when drilling rocks of different strength.
