Bridge Slotted Screen is a high-performance well screen designed for sand control in oil & gas wells. Featuring precision-cut slots (0.1–3mm), it prevents sand ingress while maintaining optimal flow rates. Made from corrosion-resistant materials (316L SS/Alloy 625), it suits high-temperature and high-salinity environments. Ideal for horizontal wells, gravel packing, and water injection systems.
1. Product Definition
The Bridge Slotted Screen is a sand control device featuring bridge-shaped slots punched on a stainless steel sleeve wrapped around a perforated base pipe. Key innovations:
- •
Slot Design: 0.5–5mm openings formed by raised "bridges," preventing sand clogging and enabling self-cleaning
- •
Materials: 304/316L stainless steel for corrosion resistance (H₂S/Cl⁻ compatibility)
- •
Strength: Collapse resistance reaches 90% of casing strength (≥655 MPa for P110 grade)
2. Key Applications
- •
Oil & Gas: High-pressure wells (e.g., X70 steel in Middle East fields) and gravel-packed horizontal wells
- •
Water Wells: Groundwater extraction with 40m³/h flow rate (0.5mm slots for fine sand)
- •
Geothermal: Brine reinjection in ≤150°C environments (Southeast Asia projects)
3. Performance Advantages
- •
12% Open Area: Higher flow capacity vs. slotted screens (≤3%)
- •
Cost Efficiency: 30% lighter than wire-wrapped screens, reducing installation costs
- •
Customization: Slot width adjustable to 0.2mm for fine-sand control
