CDI211 Series Drag Frac Packer for Horizontal Well Perforating & Fracturing Tubing String

Solving poor seal verification in horizontal well fracturing.
Lift-lower setting bottom seal tool with internal balancing/reverse flow valve, realize seal verification and backwashing, repositionable for repeated setting, ideal for horizontal well perforating and fracturing tubing string drag operations.

Main Advantage & Solution

1: No seal verification function causes blind construction in fracturing;
Solution: Built-in balancing valve and reverse flow valve, realize on-site seal verification and backwashing, avoid construction failure.
2: Packer cannot be repositioned causes repeated running in hole;
Solution: Reusable and repositionable design, support repeated setting for multi-stage fracturing, improve operation efficiency.
3: Poor bottom sealing in horizontal well fracturing causes fluid channeling;
Solution: Specialized bottom seal structure, perfect for perforating and fracturing tubing string drag operations, reliable zonal isolation.
