AP08857201 – Development of a highly efficient rock cutting tool for drilling wells equipped with synthetic diamonds and composite diamond-containing cutters with high strength and heat resistance

The main objective of the project: Development of a highly efficient rock cutting tool for drilling wells in hard and abrasive rocks based on new types of multicomponent metal-matrix diamondcontaining composites with high performance characteristics, and taking into account the features of the phenomena that occur in the rock during the introduction of diamond grains

The relevance of the project: Improving the efficiency of rock destruction with a drilling tool equipped with synthetic diamonds requires the use of diamonds of high quality with controlled characteristics of strength, heat resistance and uniformity of composition.

Scientific adviser: Doctor of technical sciences, Professor, Boranbay Tovbasarovich Ratov

Results obtained: The research substantiated and experimentally validated the design solutions of diamond drilling bits for hard rock destruction. It was demonstrated that a multilayer matrix structure with alternating impregnated and non-diamond layers, as well as a screw-type arrangement, improves rock-breaking efficiency. The addition of nano-sized CrB₂ significantly reduces friction coefficient and wear rate of the matrix material. It was confirmed that reducing diamond grain size and applying preliminary metallization enhances wear resistance and tool performance. Laboratory and field tests showed an increase in bit service life by 1.5–2.5 times and improved drilling efficiency. Technological documentation and manufacturing tooling were developed, including CNC-based production of experimental bit components. The obtained results were implemented in pilot drilling and verified under industrial conditions.
