AI Technical Summary
Technical Problem
Current packer assemblies are unable to withstand high-pressure, high-temperature underground conditions, leading to potential failure and loss of sealing integrity.
Method used
Incorporation of an anti-extrusion sleeve with deformable petals or a continuous wall, which expands to contain a backup ring, and a backing ring with a spiral groove, allowing the sleeve to deform and trap the backup ring, preventing extrusion during packer expansion.
Benefits of technology
The solution enhances the packer assembly's ability to maintain sealing integrity under high-pressure, high-temperature conditions by preventing the extrusion of backup rings and maintaining a labyrinth seal, ensuring reliable well operation.
