Abstract
Inflatable packers are provided with one or more components to improve longevity and/or functionality. One or more of the packer components utilizes reinforced materials incorporated in a manner that enables the improved longevity and/or functionality.
Claims25
An inflatable packer comprising:
- a slat for use in the inflatable packer, the slat comprising:
- a body member having a length, a width and a thickness, wherein the body member comprises at least one of an elastomer, a thermoplastic elastomer, an elastoplastic, or a polymer;
- and
- a plurality of reinforcement members disposed throughout the body member of the slat, the reinforcement members formed in a braided structure in the body member of the slat, wherein the reinforcement members comprise at least one of a fiber, a nanofiber, or a nanotube, and wherein at least a portion of the reinforcement members are exposed at an outer surface of the slat for anchoring the slat and the packer during use thereof.

An inflatable packer comprising:
- a slat for use in the inflatable packer, the slat comprising:
- a body member having a length, a width and a thickness, wherein the body member comprises at least one of an elastomer, a thermoplastic elastomer, an elastoplastic, or a polymer;
- and
- a plurality of reinforcement members disposed in the body member of the slat, the reinforcement members formed in a woven structure in the body member, wherein the reinforcement members comprises at least one of a fiber, a nanofiber, or a nanotube, and wherein at least a portion of the reinforcement members are exposed at an outer surface of the slat for anchoring the slat and the packer during use thereof.
1 more element
An inflatable packer comprising:
- a bladder;
- a cover, the bladder and the cover comprising at least one of an elastomer material, a thermoplastic elastomer material, an elastoplastic material, or a polymer material;
- a plurality of interacting slats disposed between and along the length of the bladder and the cover, each of the slats comprising an elastomer modified by reinforcement members disposed throughout a body of each of the slats, wherein the reinforcement members are disposed in an axial direction across the slats to carry a mechanical loading on the slats, and wherein the reinforcement members comprise at least one of a fiber, a nanofiber, a nanotube, or a nanoparticle and wherein at least a portion of the reinforcement members are exposed at an outer surface of the slat for anchoring the slat and the packer during use thereof.
An inflatable packer comprising:
- a bladder comprising at least one of an elastomer material, a thermoplastic elastomer material, an elastoplastic material, or a polymer material;
- a plurality of interacting slats disposed along the length of the bladder, each of the plurality of slats having slat reinforcement members disposed throughout a body of each of the slats, wherein the reinforcement members comprise at least one of a fiber, a nanofiber, a nanotube, or a nanoparticle and wherein at least a portion of the reinforcement members are exposed at an outer surface of the slat for anchoring the slat and the packer during use thereof;
- and
- a cover comprising at least one of an elastomer material, a thermoplastic elastomer material, an elastoplastic material, or a polymer material and covering the plurality of slats, the cover defining at least one opening such that at least a portion of the exposed reinforcement members in the plurality of slats are exposed to facilitate anchoring of the inflatable packer against a surrounding wellbore wall during expansion of the inflatable packer.
