    摘要: A rubber pocket is described that is suitable for use on tubing, such as a packer-type seal, on casing, such as a cement-type seal, or on liners. The rubber pocket may contain cement particles, rubber particles, swellable particles, cement filled rubber particles, cement filled swellable particles, calcium oxide, magnesium oxide, magnesium sulfate, iron (III) oxide, calcium sulfoaluminate, clay, magnetic particles and/or reactants such as crosslinkers, retardants or epoxy. The particles may be bulk spheres, bulk fibers, hollow spheres, hollow fibers, etc. The rubber pocket or bladder may also be fully or partially filled with fluids such as polymer reactants. The pocket may also be empty or contain a small volume of reactants. The slurry or epoxy or other type of fluid and granular solid or injectable matter can be injected after the completion positioning downhole.
