Product Overview
Our sliding sleeve shift tool is a dedicated downhole actuation tool designed to open, close or adjust the position of production sliding sleeves via coiled tubing, slickline or wireline runs. The tool adopts retractable locking lug assemblies at both ends to securely engage the internal profile of target sliding sleeves; operators apply tensile or torsional force from surface to shift the sleeve and switch wellbore flow channels. Precision CNC machined from high-strength forged alloy steel, the modular segmented body improves structural flexibility to adapt to minor well deviation. Hardened locking lugs deliver excellent wear resistance for repeated sleeve engagement cycles. Multi-stage internal sealing prevents well fluid from entering tool cavities. Sour-resistant metallurgy options comply with NACE MR0175 standards for H₂S/CO₂ corrosive wells. This tool is widely used for zonal production control, selective injection, temporary zone isolation and post-frac flow adjustment.

Typical Applications
- Selective opening/closing of production sliding sleeves for zonal oil/gas production
- Multi-zone water/gas injection adjustment during reservoir management
- Post-stimulation flow path switching for fractured wells
- Temporary zone isolation via sleeve shutoff for well intervention
- Coiled tubing workover in vertical, deviated and horizontal wells
- Sour well zone control with H₂S/CO₂ present downhole environments
- Wireline/slickline operated sliding sleeve adjustment jobs
Advantages Over Conventional Shift Tools
- Modular body structure improves bending tolerance, lowers stuck risk in curved well sections
- Replaceable locking lugs avoid scrapping the whole tool after lug wear to cut operating cost
- Higher combined tensile & torsional capacity enables both pull and rotary shifting operations
- Optimized sealing structure prevents sand and corrosive fluid ingress to extend tool service life
- Multiple lug profile options reduce need for dedicated custom tools for different sleeve models
- Smooth outer surface minimizes casing scratch while running in and pulling out of wellbore
FAQ
