Product Overview
ZRTS mechanical retrievable packer adopts mature mechanical setting & retrieval structure, bidirectional slip and rubber sealing system, reliable sealing performance and repeated use capability. Its mechanical setting mechanism eliminates the need for hydraulic setting tools or wireline setting equipment, making it particularly suitable for coiled tubing, slickline and workover operations where surface rotation or reciprocation is available. The packer can be set and released by simple tubing manipulation, reducing operational complexity and equipment requirements. Constructed from high-strength alloy steel with anti-corrosion treatment, it handles demanding downhole conditions including H₂S and CO₂ environments.
Core Features & Benefits
- Fully mechanical setting and retrieval, no hydraulic or explosive setting devices required

Typical Applications
- Multi-layer pressure / production testing of oil & gas wells
- Segmented acidizing, scale removal and reservoir stimulation operations
- Temporary zonal isolation for water shutoff remediation
- Stratified water injection allocation for injection wells
- Zonal isolation in H₂S/CO₂ sour well workover
- Temporary isolation during remedial cementing jobs
- Post-frac temporary isolation for wellbore cleanup
Advantages Over Ordinary Mechanical Retrievable Packers
- Optimized slip tooth profile improves grip on casing inner wall, reduces casing damage while enhancing anchoring reliability
- Upgraded anti-extrusion backup structure extends packing service life under long-duration high differential pressure
- More tolerant of minor casing deformation, still maintains effective sealing in slightly deformed casing intervals
- Refined unlocking mechanism lowers risk of stuck retrieval after long downhole placement
- Modular sealing stacks can be individually replaced, extending main housing service life
- Broader available elastomer options adapt acid, fracturing fluid and other complex treatment media
FAQ
Q: How is the ZRTS packer set?
A: It is set by mechanical rotation or reciprocation of the tubing string. No hydraulic or explosive setting tools are required.
Q: Can the packer be re-used?
A: Yes, the ZRTS packer is designed for multiple set and release cycles, making it ideal for multi-zone operations.
Q: What casing sizes are available?
A: Standard sizes cover 4 1/2", 5 1/2" and 7" casing. Custom sizes are available upon request.
Q: Is H₂S service available?
A: Yes, NACE MR0175 compliant material options are available for sour service environments.
