Abstract

1,086,113. Wells &c. BAKER OIL TOOLS, Inc. March 30, 1965 [April 22, 1964 (2)], No. 13434/65. Heading E1F. A packer A comprising a tubular body 10, 11, 11a carrying a resilient packing 23 has a valve 95 movable between lower and Upper positions to close the ports 90. The packer is lowered into position in the well casing B on a running string connected to a member-50 of asetting tool C, the member having extensions 52 109 and the extension 109 engaging the valve. At the required position of the packer the string, the member and extensions are rotated to the right, a slip setting and retaining structure 61 being held against rotation by a drag member 66 so that a nut 72 is freed from the member 50 which with the extensions and the packer is then moved downwardly by the string until the slips 28 are freed from a sleeve 60 and expanded by springs 45. The string is lifted to cause the expander 24 to set the slips 28, and to shear a screw 25 to permit the body to move upwardly to expand the packing against the casing, the body 'being held in the packing compressing position by a ratchet lock ring 33. Further lifting of the string shears the screws 17, and sets the slips 12 and the packer. After a screw 53a has been sheared by upward pull on the string the extensions may be moved upwardly until a stop 52b engages a nut 53 when the string may be rotated to the right to unthread the nut 53 from the body so that the string member 50 the extensions and the structure C may be removed from the well. The extension 109 may be run into the packer on another tubular string. When the packer is run into and set in the casing the valve is held by the latches 100 so that the space below the packer is in communication with the interior of the string through the ports 90, the extensions, and the member 50. After the packer has been set and the screw 53a has been sheared upward pull on the string closes the ports. When the string is raised to remove the extension 109 the ports are closed, the valve being retained in position by the engagement of the latches with a groove 103.
