Abstract

Настоящее изобретение относится к устройству (1) для модификации боковых стенок скважины. Устройство содержит продольный корпус (2), выполненный с возможностью входить в ствол скважины. Корпус включает в себя первую концевую часть (11), вторую концевую часть (12) и боковую часть (13), расположенную между боковыми частями (11, 12) и выполненную с возможностью прилегать к боковым стенкам скважины. Средство (5) расположено на боковой стенке корпуса (2) для удаления материала с боковой стенки скважины. Корпус (2) выполнен с возможностью вращаться с контролируемой скоростью вращения относительно стенок скважины и подаваться с контролируемой скоростью продольного перемещения относительно ствола скважины. Изобретение относится также к способу для создания скважины с внутренними винтовыми углублениями.
