Product Overview
ZCP-Ⅰ mechanical retrievable packer is a mechanically set and retrievable zonal isolation tool designed for coiled tubing, workover and completion operations. It utilizes a proven mechanical setting mechanism that can be actuated by tubing rotation or reciprocation, eliminating the need for complex hydraulic setting assemblies or wireline explosive charges. The packer features an advanced bidirectional slip system and high-performance rubber sealing element with anti-extrusion backup rings, providing reliable annular isolation under high differential pressure and temperature conditions. Its through-bore design allows passage of well intervention tools, enabling through-tubing operations below the packer. Manufactured from corrosion-resistant alloy steel, it is available in standard and sour service material grades complying with NACE MR0175 / ISO 15156 standards.
Core Features & Benefits
- Mechanical rotation or reciprocation setting, no hydraulic or wireline tools needed
- Bidirectional slip anchoring system for tension and compression loads
- High-performance rubber element with anti-extrusion rings for reliable sealing
- Large through-bore for tool passage below the packer
- Multiple set and release cycles for multi-stage operations
- NACE MR0175 compliant for H₂S and CO₂ environments
- Full-open bore design minimizes flow restriction during production and stimulation
- Available in standard casing sizes with custom configurations

Typical Applications
- Layered pressure testing and production testing of oil & gas wells
- Segmented acidizing, plugging removal and reservoir stimulation operations
- Temporary zonal isolation for water shutoff workover
- Temporary well abandonment and later packer retrieval
- Sour well isolation with H₂S/CO₂ corrosive formation fluid
- Injection well layered water injection allocation
- Intermediate isolation during multi-stage remedial cementing
Advantages Versus Hydraulically Set Retrievable Packers
- Mechanical operation removes reliance on hydraulic setting tools, lowers downhole assembly complexity and tripping runs
- Bidirectional slip anchoring provides stronger displacement resistance for bidirectional pressure differential scenarios
- Robust mechanical locking reduces risk of accidental unset caused by pressure fluctuation
- Wider selection of elastomer materials adapts various treatment fluid chemistries
- More convenient on-site operation, less requirement for precise pumping parameter control
- Lower maintenance cost as worn packing stacks can be replaced individually for repeated tool body usage
FAQ
Q: What setting methods are supported?
