ABSTRACT:
In subterranean wells, it is common to effect the radial expansion of an annular organic sacking element into sealing engagement between a tubular inner body and the inner wall of a well conduit, such as a well casing. Extrusion of the organic material has been encountered between the inner surface of upper and lower cone elements and the exterior of a tubular body portion and also between the inclined surfaces of upper and lower cone elements and the cooperating surfaces of cone rings. The first mentioned extrusion path is eliminated by forming a generally radial surface on the inner end of the upper and lower cones orthogonal to the tubular body, and inserting a carbon fiber filled organic material in the resulting annular chamber. The extrusion path between the inclined surface of the cone and the cooperating surface of the cone ring is minimized by utilizing the forces exerted by the compressed sealing material of the packing element in combination with to effect the shearing of the inner vertex portion of a packer ring along a plane that corresponds exactly to the inclined surface of the cone ring.
