冲孔板性能特点
Performance characteristics of punching plate
1、多层防砂过滤套具高效防砂性能，能更好地阻挡地层砂粒，满足井下防砂需要。
1. The multi-layer sand control filter sleeve has high efficiency sand control performance, which can better block the formation sand and meet the needs of downhole sand control.
2、滤孔均匀，渗透性及防堵性能高。
2. Uniform filter hole, high permeability and anti plugging performance.
3、过滤面积大，流动阻力蠕动泵 保定网站建设 保定网站制作 保定网络公司 保定办公家具 保定轻钢别墅 小，出油率高
3. Large filtration area, small flow resistance and high oil yield
4、不锈钢材质的优异抗腐蚀性能，抗酸、碱、盐腐蚀，可适应油井的特殊要求，缝隙不会因腐蚀而逐渐变大。
4. The stainless steel material has excellent corrosion resistance, acid, alkali and salt corrosion resistance, which can meet the special requirements of oil wells, and the gap will not gradually become larger due to corrosion.
5、多层结构焊接一体，可使滤孔稳定，抗变形能力极强。
5. The multi-layer structure is welded together, which can make the filter hole stable and has strong deformation resistance.
