| titleOfInvention | Packing element, packer and bridge plug including wire sealing ring |
| abstract | This application involves field of sealing technology, more particularly to packing element, packer and the bridge plug including wire sealing ring that can bear high temperature and pressure used in a kind of oil exploitation industry.Packing element includes wire sealing ring and fiber filament sealing ring, and wire sealing ring is inconsistent with fiber filament sealing ring and is arranged below；Wire sealing ring includes cross one another more one metal wires and colloid that each wire bonds together；Fiber filament sealing ring includes cross one another high-temperature and high-presure resistent plurality of fibers silk and colloid that each fiber filament bonds together.When the lower section of fiber filament sealing ring is arranged in the wire sealing ring of the application, wire sealing ring passes to the axial compressive force of fiber filament sealing ring because that can reduce with the friction of central tube and/or casing, the axial compressive force that fiber filament sealing ring is subject to can effectively be reduced at this time, and shoulder Producing reason is that axial compressive force is excessive, so this design the generation that can reduce or prevent shoulder. |
