2.The keystone slot is narrower on the outside surface of the pipe than on the inside.
3.Slots formed in this way have an inverted “V” cross-sectional area and are less prone to
plugging because any particle passing through the slot at the outside diameter (OD) of the
pipe will continue to flow through, rather than lodging within the slot.
4.While the slotted liners are usually less costly than wire-wrapped screens, they have smaller
inflow areas and experience higher pressure drops during production.
5.Slotted liners also plug more readily than screens; they are used where well productivity is
small and economics cannot support the use of screens.

1.The slotted liner is mainly used to the water and oil reservation layer without much sand.
2.Its function is to prevent the rock bits dropping into the well bore.
3.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 bridge,and thereby
achieving the anti-sand purpose.
4.This type of product is commonly used to sand rock and carbonate reservoir,and especially
useable for horizontal wells.
