CDI341 Series Hydraulic Injection Packer for Staged Water Injection & Acidizing

Solving poor zonal isolation in staged water injection/acidizing.
Hydraulically set compression packer with reverse well-washing capability, reinforced rubber sleeve for high pressure resistance, ideal for oil & gas well staged water injection, acidizing and plugging operations.

Main Advantage & Solution

1: Unstable sealing in water injection/acidizing causes cross-layer fluid channeling;
Solution: Hydraulic setting compression structure, reliable zonal isolation, no fluid channeling in long-term injection.
2: Rubber sleeve damage under high pressure reduces service life;
Solution: Rubber sleeve with protective cover, enhance pressure resistance and anti-corrosion performance.
3: Wellbore cleaning difficulty after operation increases construction time;
Solution: Built-in reverse well-washing function, realize efficient wellbore cleaning without additional tools.
