Precision composite screen

From the inside to the outside, it is composed of a base pipe, an inner sheath, a composite sand control filter sleeve, and a stainless steel outer protective sleeve. The composite sand control filter sleeve is formed by composite rolling of stainless steel mat meshes with different filtering pores and then integrally welded.

Performance characteristics:

1. Multi-layer stainless steel precision woven mesh composite filter layer, high sand control reliability

2. The ability to resist extrusion and bending deformation is strong, and the sand control ability remains unchanged when the radial deformation is 40%, which meets the requirements of horizontal wells.

3. Large filtration area, low flow resistance, high output

4. The size of the filter hole is precisely controllable (error <10 microns), and the filter hole is stable and not deformed

5. Uniform filter holes, high permeability, strong anti-blocking ability, blocking period is 2 to 3 times that of ordinary screens, and easy to backwash

6. The base pipe is a standard casing or tubing, and the filter layer is made of high-quality stainless steel. It has strong corrosion resistance and can resist CO2, Cl-, H2S corrosion, and is suitable for acidizing operations

7. Small outer diameter, light weight, easy to push in place on the long-distance horizontal section
