摘要: The well reamer comprises a sub for attaching it to the drive means, a hollow housing with a central channel and radial openings in its side wall, projectable rolling cutters with shanks, mounted in the radial openings of the housing, and a mechanism for projecting the rolling cutters, including a piston and a member for locking the rolling cutters in their operating positions. The annular piston is connected with the housing for joint rotation therewith, and is regidly connected with the sub. The wall of the piston has radial passages made therein, establishing communication between its central channel and so annular space defined between the walls of the piston and of the housing. The member for locking the rolling cutters is accommodated with a clearance in the central channels of the piston and of the housing, and has an annular shoulder. The central channel of the piston defines a seat for engagement with the annular shoulder of the locking member.

摘要: The device is intended for expanding profile pipes set in a well for patching off a troublesome zone, and also for straightening crumpled casings.The device comprises a housing (1) having an expanding member (3) mounted thereon in bearings (4, 5) on a journal (2) extending at an acute angel to the longitudinal axis of the housing (1). The expanding member (3) is shaped as a spherical segment (9) having its external surface defined by alternating portions of a spherical surface (10) and the lateral surfaces of cylinders (11) whose geometric axes being to a plane perpendicular to the axis (13) of the journal (2).
