Improvement of cutting structures of a single-cone drill-bit
The paper presents the results of research on the study of the operation and development of a new design of cutting structures of a single-cone drill-bits. Recommendations are given on the creation of toothed-type cutting structures of single-cone drill-bits, providing an increase of the main operational indicators of this type of a drilling tool. The paper also presents the analysis of the impact of the shape, size of the rock-cutting elements, the dynamics of the rock loading when it encounters teeth of various configurations, as well as other factors: the specific load under the cutting edges and its role in ensuring a high mechanical drilling speed and general performance indicators of a single-cone drill bit, initial materials for its manufacture, and the nature of the interaction of the drill bit teeth with the well bottom rock on the intensity of the well bottom destruction.
