Изобретение используют для бурения скважин. Цель: гашение колебаний, возбуждаемых в результате силового взаимодействия с забоем зубков шарошечного долота в процессе бурения скважин. Сущность изобретения: в наддолотном амортизаторе, содержащем корпус с присоединительными резьбами, корпус выполнен в виде выпуклой оболочки вращения из упругого материала. Положительный эффект: обеспечивается защита бурильной колонны от колебаний.The invention is used for drilling wells. Purpose: damping vibrations excited as a result of force interaction with the face of the teeth of the cone bit during the drilling of wells. SUMMARY OF THE INVENTION: in a supra-bit shock absorber containing a body with connecting threads, the body is made in the form of a convex shell of revolution of elastic material. Positive effect: the drill string is protected from vibrations.
