DEVELOPMENT OF ROCK CUTTING TOOL WITH PDC CUTTERS
Известия Томского политехнического университета: Инжиниринг георесурсов, 2020 Relevance. When developing a tool for drilling wells for various purposes, the main optimization criteria are the increase in mechanical speed and its resource. This is especially true for rock cutting tools intended for drilling in changing geological conditions of deep and inclined wells.
