Un écran de contrôle du sable à haute résistance avec un motif de fentes de pont décalées, offrant à la fois une capacité de débit élevée et des performances anti-colmatage pour les puits de pétrole/gaz/eau.
Slot Design:
Bridge-type: Interlocking slots prevent straight-through sand passage
Slot Width: 0.1mm~3mm (customizable), tolerance ±0.02mm
Slot Length: 20~50mm (optimized for flow/strength balance)
Material & Process:
Base Pipe: SS304/316, carbon steel (Ni-P coated)
Laser Cutting: Burr-free edges, high precision
Surface Finish: Electropolishing (EP) or sandblasting
Advantages:
Sand Retention: Blocks particles ≥0.1mm (matched to slot width)
Flow Area: 15%~30% (higher than wire-wrap screens)
Strength: Axial crush ≥50MPa, collapse ≥20MPa
✔ Unconsolidated sand reservoirs
✔ Horizontal well multi-stage completion (with packers)
✔ Water injection/geothermal well filtration
