Устройство относится к раздаче труб роликами и предназначено, в частности для развальцовки перекрывателей из профильных труб, устанавливаемых в скважинах. Цель изобретения - повышение надежности и долговечности устройства. Устройство содержит полый корпус с выполненными на его боковой поверхности наклонными к продольной оси корпуса плоскостями, на которых с помощью опорных пластин и осей установлены вальцующие элементы. При этом наклонные плоскости корпуса выполнены в виде цилиндрических цековок, оси симметрии которых совпадают с осями симметрии вальцующих элементов. Причем оси этих элементов жестко и эксцентрично закреплены на опорных пластинах, а на наклонных плоскостях корпуса выполнены эксцентрично смещенные относительно их поверхностей к нижнему концу корпуса углубления, в которых установлены и зафиксированы от проворота опорные пластины. Устройство на колонне бурильных труб опускают в скважину до предварительно установленного в ней перекрывателя из профильных труб. Затем вращением колонны бурильных труб вместе с устройством выправляют внутреннюю поверхность профильных труб до плотного прижатия их стенок к стенке изолируемого участка скважины.The device relates to the distribution of pipes with rollers and is intended, in particular, for the flaring of flooring blocks from core pipes installed in wells. The purpose of the invention is to improve the reliability and durability of the device. The device comprises a hollow body with planes inclined to the longitudinal axis of the body on its side surface, on which roller elements are mounted on the support plates and axes. In this case, the inclined planes of the body are made in the form of cylindrical baffles, the axes of symmetry of which coincide with the axes of symmetry of the roller elements. Moreover, the axes of these elements are rigidly and eccentrically fixed on the supporting plates, and on inclined planes of the body there are recesses eccentrically displaced relative to their surfaces to the lower end of the body, in which the supporting plates are installed and fixed from rotation. The device on the string of drill pipe is lowered into the well to the pre-installed in it a blocker from the profile pipe. Then, rotating the drill pipe string together with the device straightens the inner surface of the core pipes until their walls are tightly pressed against the wall of the insulated well section.
