ÉCRAN ENROULÉ DE FIL
1. Product Definition
The Wire-Wrapped Screen is a high-performance sand control device constructed by helically winding V-shaped wires around longitudinal support rods, with each intersection fusion-welded. Key features include:
- •
Slot Design: 0.025–2.0mm trapezoidal openings for anti-clogging and self-cleaning
- •
Materials: Stainless steel 304/316L (corrosion resistance) or API-grade base pipes (e.g., N80/P110)
- •
Strength: Collapse resistance reaches 90% of same-size casing
2. Key Applications
- •
Oil & Gas:
- •
Gravel packing in horizontal wells (slot 0.1–0.3mm for sand retention)
- •
Thermal recovery (316L withstands 350°C steam)
- •
- •
Water & Geothermal:
- •
Deep-water wells (40m³/h flow rate, slot 0.2mm)
- •
Geothermal brine reinjection (pH 2–12 compatibility)
- •
- •
Industrial Filtration:
- •
Mining slurries (high wear resistance), Chemical acids (316L anti-corrosion)
- •
3. Performance Limits
- •
Cost: 40% higher than slotted screens, justified in high-flow or corrosive environments
- •
Fine Silt: Upgrade to sintered mesh for particles <0.1mm
4. Compliance & QA
- •
API RP 61: Sand control performance validation.
- •
ISO 9001: Mandatory weld consistency certification
