Filter material: 302, 304, 304L, 316, 316L stainless steel wire and low carbon steel wire, galvanized iron wire, etc.
1. Multilayer sand control filter sleeve has high sand control performance, which can better block formation sand grains and meet the needs of underground sand control.
2. Large filtration area, small flow resistance and high oil yield;
3. Welding of multi-layer structure can make the filter hole stable and have strong anti-deformation ability. The anti-extrusion and anti-bending deformation ability is strong, and the sand control ability is unchanged when the radial deformation is 40%, which meets the requirements of horizontal wells. 4. The size of the filter hole can be controlled (error is 5 microns), and the filter hole is stable and not deformed.
5. Uniform filter hole, high permeability, strong anti-blockage ability, blockage cycle is 2-3 times of ordinary sieve tube, and easy to backwash; 6. Base pipe is standard casing or tubing, filter layer is high-quality stainless steel material, strong anti-corrosion ability, can resist CO2, CL-, H2S corrosion, adapt to acidizing operation;
7. Small outer diameter, light weight, easy to push in place in long-distance horizontal section.
Purpose: Stainless steel sand control screen pipe is used in various oil wells, vertical wells, sidetracking wells, horizontal wells, water wells and steam drive wells on land and offshore.
