Abstract

1,192,795. Well packers. DRESSER INDUSTRIES, Inc. 8 Sept., 1967 [26 Sept., 1966], No. 41226/67. Heading E1F. A retrievable bridge plug for a well bore has a packer assembly 145 on a mandrel 25, expandable wall grips 101 and 181 above and below the packer assembly and a sleeve valve 75 at the top of the mandrel for blocking the central bore 69 of the mandrel. The plug is lowered into the well on a tube string 2 with a connector 3 which has J-slots 16 engaged by gudgeon pins 38 on the mandrel. The connector also engages a flange 80 on the valve 75 to hold it open, i.e. to align the ports 33 in the mandrel wall with the apertures 79 in the valve, but when the connector disengages collets 17 in the connector engage pads 82 to lift and close the valve. The pads are spring loaded to retract into a recess 30, to enable the connector to be disengaged from the mandrel. The packer assembly 145 comprises sleeves 129, 150 which are moved relatively to expand the packing rings 146 against the bore wall. The assembly also has tapered expander elements 112, 157 which engage the grips 101, 181 to expand them against the wall. The upper grips are mounted on a setting sleeve 90 resiliently mounted on the mandrel, and the lower grips are mounted on a recovery sleeve 158 located on the mandrel by gudgeon pins 162 and J-slots 65 (also in Fig.VI, not shown). The plug is set by rotating and lowering the mandrel 'so that the J-slots 65 moves past the pins 162 until the pins are in the upper part of the J-slot (shown in broken lines). As the mandrel is lowered the setting sleeve 90 enters the chamfered part 114 of the upper expander element 112, which is segmented, and separates the segments'. The upper grips 101 then engage the element 112 and are expanded against the wall of the bore. The lower J-slot has a circumferential extension to form, an abutment by which the mandrel can be raised' to expand the lower grips 181 against the wall of the bore. The connector 3 is then disconnected, closing the valve 75. When the mandrel is lowered, a seal 140 on the mandrel engages the inner surface of the packing assembly sleeve 129 and an abutment 143 immediately below the seal engages an abutment 133 on the sleeve so that fluid passageways by-passing the packing are closed, and so that a downwardly acting pressure differential is transmitted to the sleeve to expand the packing material against the wall of the bore. An upwardly acting pressure differential is transferred to the packing material through abutments 161 and 155 which are also in contact. The plug is retrieved by reversing the above operations, the grip of the upper grips 101 being broken when the setting sleeve 90 is retracted from within the element 112.
