摘要

is u0441u043au0432u0430u0436u0438u043du043du044bu0439 tool containing the search surface, the axis of the compression surface and at least one of the valid elementa compressive surface attachments to the node with the possibility of russia and with the possibility of establishing a spring attached to the team site element.u0441u043au0432u0430u0436u0438u043du043du044bu0439 tool is made with possibility of rotation about the axis of drilling toolin which at least one surface has a transverse compressive force on the wall of the borehole.also has a u0444u0438u043bu044cu0442u0440u0430u0446u0438u043eu043du043du043eu0439 crust formation, which produces drilling fluid and drilling fluid in contact with the wall of barrel wells.
