DEVELOPMENT OF DIAMOND DRILLING BIT FOR DIRECTIONAL DRILLING
Известия Томского политехнического университета: Инжиниринг георесурсов, 2022 The relevance. Many years of experience in directional drilling has made it possible to identify complex mining and geological conditions in which the use of deflectors leads to decrease in the effectiveness of the curvature and accidents. So, for example, the fastening of continuous deflectors in hard, very hard and abrasive rocks, when the borehole ...
