The article discusses the advantages of using cryogenic technology in the production of gravel filter elements. A method for calculating the main components for the production of temporarily monolithic annular gravel elements is described. An approach has been developed for the strength analysis of annular gravel filter bits, taking into account installation conditions and the effect of water flow in the aquifer. An analytical calculation was performed to determine the distribution of gravel packing in the behind-...

The article presents directions for improving diamond drill bits designed for drilling in hard abrasive rocks. The first direction involves the development of multilayer tools in which impregnated diamond layers are separated by soft, non-diamond interlayers of the same configuration. Additionally, ring-shaped bits have been developed with diamond-bearing layers placed on the concave surface of the matrix. This design enables the use of a weakened rock zone beneath the working elements, enhancing rock-breaking eff...
