The article justifies the need for technological solutions in the use of polymer-composite materials in order to limit the impact of dynamic frictional forces in oil drilling. The relationship between macrostructural surfaces was investigated, in particular increasing the effectiveness of the axial load on the drill bit during drilling directional and horizontal wells. It is established that the polymer coating of drill string elements (BC) based on fluoroplastic brand F-4, with a small thickness of 2 ? 3 mm and t...
