铁板冲孔板的特点
Features of iron plate punching plate
1、具有高效防砂性能，能更好地阻挡地层砂粒，满足井下防砂需要。
1. It has high efficiency sand control performance, can better block the formation sand, and meet the needs of underground 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，外保护套也可螺旋焊接。
5. The multi-layer structure is welded together, which can make the filter hole stable and has strong deformation resistance. The outer protective sleeve can also be spiral welded.
