1. The filter structure of double-layer stainless steel metal dense grain filter screen is adopted, with high sand control reliability and strong damage resistance (referring to type A);
2. An intermediate support discharge screen is added in the middle of the double-layer filter screen to improve the flow characteristics (referring to type A);
3. Screen sleeve structure, large flow area and high output;
4. Small outer diameter, light weight and high strength, which is easy to push in place on long-distance horizontal sections;
5. Acid and alkali resistance, high temperature resistance and long service life;
6. Uniform filter holes, high permeability and strong anti blocking ability;
7. Strong deformation resistance. After 75% and 40% diameter deformation, the performance is still intact, and the sand production has not increased, which meets the requirements of horizontal wells;
8. Processing technology: the filter layer is non-destructive welded, with high strength and strong damage resistance;
9. The construction is simple and easy to operate, which is conducive to reducing the construction cost and improving the construction success rate
