The working principle is allowing the certain size sand coming through the surface with crude oil but keeping the bigger size sand being stopper outside to form sand bridgeand thereby achieving the anti-sand purpose.
This type of product is commonly used to sand rock and carbonate reservoirand especially useable for horizontal wells.
Trapezidal design
Reduce the rate of erosion of sewing caused by system, improve self-cleaning, maintain the slot cavity open, and improve the recovery efficiency.
Groove Structure Length(mm):0.20-1.20
Longitude slot design (rectangular slot)
Reduce friction of fluid entrance, open area of the fluid and processing are easily control. This design is mainly for thick reservoirs, similar pressure and other physical reservoirs and also loose sand reservoirs with medium coarse particles.
Composite slot design
Take the rate of crude oil seepage flow, flow resistance and lifetime into account, a combination of various slot. This slot is particularly design for complex reservoirs with different pressures. But the manufacture technology of composite slot is complicated and difficult
