Advanced Dual-Layer Prefilled Filter Screen Pipe: The Ultimate Sand Control Solution
From 3D Design to Real Precision
The pre-filled filter screen tube adopts a structure of “stainless steel metal base tube + ceramic ball pre-filled filter layer”:
Pre-filled filter layer: ceramic balls as the core filter material (without resin bonding) are filled between the base tube and the outer protective mesh to form a high-precision filter medium;
When traditional gravel packing is not feasible, Yanzhao pre-packed wire-wrapped screens offer a premium alternative for sand control and can be fully customized through a wide range of filtration media options.
Precision Gap : Customizable filtering slots down to 0.05mm for superior sand retention.
Double-Layer Security : Inner and outer wedge wire screens provide structural integrity and secondary filtration.
Flexible Media Filling : Pre-filled with high-strength Ceramic Balls or Silica Sand to suit various geological conditions.
Anti-Corrosive : Available in SS304, 316L, or specialized alloys for long-term underwater durability.
Traditional screens often struggle with fine sand infiltration, leading to pump damage. Our Prefilled Filter Screen acts as a built-in gravel pack. By integrating the filter media directly between two layers of wedge wire, we eliminate the need for complex downhole gravel packing, saving you significant installation time and costs

Core Advantages (According to Contractor/Owner Needs)
1. For Contractors:
– No Well Enlargement Required: Customizable to client specifications;
– Reduced Operation Time: Pre-filled design eliminates the need for on-site filter material filling, reducing drilling/completion time by 1-3 days per well;
– Accelerated Development Pace: Simplified completion process facilitates earlier production of oil and gas wells.
2. For Owners:
– Low Maintenance Costs: Ceramic balls are less prone to scaling and biofilm contamination, with a screen life of over 50 years (compared to approximately 35 years for traditional resin screens);
– Long-Term Economic Efficiency: Reduces well workover frequency and lowers manpower and equipment investment for subsequent sand control maintenance.
