FIELD: oil-and-gas production industry; operation and repair of oil wells.
SUBSTANCE: proposed mechanical packer includes mandrel and support rigidly connected with this mandrel. Located in succession under said support are sealing member, cone, holder and runner. Cone and holder may move axially relative to mandrel. Spring-loaded toothed sockets and sliding pins are smoothly located in holder over its circumference. Toothed sockets are pressed to barrel by means of springs and sliding pins are released by springs in opposite direction. One end of spacer sleeve is rigidly mounted on holder and other end is connected with rubber by means of at least one dowel pin; runner has shaped slot on its external surface. Runner is axially and radially movable relative to mandrel. Dowel pin is rigidly mounted lower portion of spacer sleeve and is received by shaped slot of runner.
EFFECT: increase of useful space for working members of packer at retained section of mandrel.
