Sealing/Packing TRIZ Cases
- Self-assembling Packer Using Magnetorheological Fluid for Annulus Sealing
Magnetorheological fluid in the packer cures into a solid seal under magnetic fields, eliminating hydraulic activation complexity and debris blockage risks.
- Composite Slip and Cone Assembly for Downhole Frac Plugs
Grooved composite slips fracture under load to expand against wellbore walls, preventing pre-setting during high-pressure horizontal drilling operations.
- Plug Piston Barrier Debris Removal Mechanism
A plug piston assembly moves a sleeve uphole to drag ruptured elastomer membranes out of the fluid flow path.
- Hanger System Sealing Wellhead Pass-Through Cables
Compressible elastomeric hanger seals wellhead pass-throughs without cutting, eliminating splicing errors.
- Slip-on Hydraulic Packer Modular Assembly
Segmented piston and sealing elements allow quick field configuration, reducing inventory needs and downtime.
- Downhole Seal Device with Unitary Core and Welded End Rings
A downhole seal device uses a unitary structure with welded end rings to mount securely on pipelines.
