| titleOfInvention | Rubber cylinder with rigid seal rings on both ends, packer, and bridge plug |
| abstract | A rubber cylinder with rigid seal rings on both ends, a packer, and a bridge. The rubber cylinder comprises a wire seal ring, a filament seal ring, and rigid seal rings. The wire seal ring abuts the filament seal ring and is disposed below the filament seal ring. The wire seal ring comprises a plurality of wires intersecting each other and a colloid bonding all the wires together. The filament seal ring comprises a plurality of high-temperature high-pressure resistant filaments intersecting each other and a colloid bonding all the filaments together. When the wire seal ring is disposed below the filament seal ring, friction between the wire seal ring and a central tube and/or a casing reduces an axial pressure transferred to the filament seal ring, Such reduction further reduces the occurrence of an extruded shoulder. |
