PPS精密冲缝筛管 PPS Screen 
产品推荐
PPS筛管的组成是由中心衬管（符合API标准的石油套管）和精密冲缝套组成。具有精密可控的缝隙，整体强度高，抗变形能力强，优良的抗腐蚀性等特点。在应用过程中，砂砾被阻挡在精密冲缝套外部，但液体可以经过缝隙进入中心衬管内部，从而达到防砂目的。
The PPS Screen is an excellent combination of central liner( in line with API casing&tubing )and PPS Shroud designed for medium sandstone reservoirs。It has the characteristics of the precision controlled slot ,overall high strength, anti-deformation ability, excellent corrosion resistance and so on.
●产品优势The Advantage of the PPS Screen
1.精密冲缝筛管具有高效防砂性能，能够更好的阻挡地层砂砾，满足井下防砂需要；
2.过滤缝隙均匀，渗透性能高及防堵性能高；
3.独特的侧流孔结构具有流动阻力小，出油率高且稳定性好的性能；
4.不锈钢材质具有优异的抗腐蚀性能，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。
1. PPS Screen with the sand control performance, better stop gravel stratum, meet the needs of the downhole sand control.
2. The filter hole even, permeability and prevent performance.
3. The filter has big filter area, small flow resistance, high yield efficiency and stable performance.
4. Stainless steel material has excellent corrosion resistance, resistance to acid, alkali, salt corrosion, can adapt to the special requirements of the well, protects cracks from growing bigger by corrosion.
●产品适用范围 The Scope Of Products
过滤管可用于直井、斜井、水平井等套管完井。同时，这种过滤管可用于油井、气井和水井。它可以单独的作为防砂过滤用，也可以在砾石充填时使用。
Screen can be used for casing completion of vertical wells, inclined wells and horizontal well etc. At the same time, it can be used for various oil wells,gas wells and water wells. It also can be used as sand control colonnade individually and be used in gravel packing.
