The improvement of the operation of roller cone bits, only drilling indicators are optimized, which include axial load, frequency of rotation, borehole diameter and rock fortress coefficient. The use of one or another roller bit can be justified by the physical-mechanical properties of rocks, which can have different values depending on the depth of drilling and the horizon. However, while resolving energy costs on the basis of the quality of the drill bits’ interaction with the physical-mechanical properties of rocks and the condition of the cutters at the bottom of the well, which require high-tech solutions with scientific bases, it is possible to make the choice and justify a more efficient design of the drill bit. The article discusses a new method for determining the patency of a drilling cone bit using the determination of the workload of teeth and crowns based on kinematic calculations. Based on the kinematic parameters, the gear ratio of the cones, the specific indicators of contact and operation of the teeth on the bit crowns are determined, which in turn show the most loaded crowns. Based on these indicators, it is possible to determine crowns that are prone to breakage during the operation of bits. By this calculation was made a new program which by geometrical parameters of the tricone drill bit can show graphics of the work cones and crowns.
