The article deals with the issues of increasing the efficiency of drilling by developing and studying the process of interaction between the teeth of the drilling tool and the rock. A model of a tricone type drill bit has been developed. When drilling wells, 70-85% of the bits used are tricone bits. For an accurate comparative analysis, two variants of a tricone drill bit were studied, a serial one and a proposed one with a diameter of 215.9 mm. The interaction of the rock destroying tool with the rock during drilling is analyzed in a complex way using the ANSYS program, which operates on the basis of the finite element method. The change in the overall speed of an optimized tricone bit during interaction with the rock is considered. According to the results of the study, the parameters of the speed of penetration of the tooth into the rock were obtained, an analysis of the equivalent stress was carried out during the interaction of serial and experimental tricone bits with the rock. Graphs of changes in the equivalent stress of the rock by the penetration of the cone elements into it depending on time for both drilling tools were obtained. The results obtained in the study of the interaction of a rock destroying tool with a rock during drilling make it possible to determine the optimal parameters for placing teeth on the cone body at the design stage of tricone type drilling tools in the development of energy efficient bits. © J.B.
