A sand control screen constructed by helically wrapping trapezoidal/triangular metal wires onto a perforated base pipe, creating continuous slots for sand retention while maintaining high flow capacity.
Slot Structure:
Slot Width: 0.1~0.5mm (customizable), tolerance ±0.03mm
Continuous Slots: 360° filtration, no dead zones
V-Shape Opening: "Narrow-outside/wide-inside" anti-clogging design
Material & Process:
Wire Material: SS316L, Monel alloy, coated carbon steel
Base Pipe: Perforated (30~120 holes/m) or slotted pipe
Welding: Resistance/TIG welding for permanent bonding
Advantages:
Sand Retention: Blocks particles ≥0.15mm
Flow Area: 8%~15% (higher than slotted pipes)
Crush Resistance: ≥15MPa collapse (with reinforcing rings)
✔ Unconsolidated sand reservoirs
✔ Open-hole horizontal completions
✔ Water injection/steam flood wells
