Abstract
Изобретение относитс к буровой технике и может быть использовано дл бурени с одновременным расширением ствола скважины или последовательного расширени предварительно пробуренной скважины. Цель - повышение надежности в работе. Расширитель скважин состоит из корпуса 1, в пазах которого на подшипниковых маслонаполненных опорах 2 и цапфах 3 посредством пробок 4 и размещенных в цапфах 3 пальцев 5 размещены шарошки 6. Со стороны периферийного и внутреннего торцов цапф 3 в их большей части и параллельно их ос м размещены лубрикаторы (Л) 10 с мембранами 11,12. При работе расширител шарошки 6 и резцы 9 разрушают породу в забое. Смазочный материал, размещенный между мембранами 11,12, выдавливаетс ими из Л 10 в подшипниковую опору 2 через каналы 13,15 и 19,20. Перед повторным спуском в скважину Л 10 заполн ют смазочным материалом. 2 ил.The invention relates to a drilling technique and can be used to drill while simultaneously expanding a wellbore or sequentially expanding a previously drilled well. The goal is to increase reliability in work. The reamer consists of a housing 1, in the slots of which, on the bearing oil-filled supports 2 and pins 3 by means of plugs 4 and placed in the pins 3 of the fingers 5, the cones 6 are placed. lubricators (L) 10 with membranes 11,12. When the expander cones 6 and the cutters 9 destroy the rock in the face. The lubricant placed between the membranes 11,12 is squeezed out of L 10 into the bearing support 2 through the channels 13,15 and 19,20. Before re-lowering into the well, L 10 is filled with a lubricant. 2 Il.
