Sand Control Screen Slotted Liner, Laser Cutting Slotted Liner
The slotted liner is mainly used to the water and oil reservation
layer without much sand. Its function is to prevent the rock bits
dropping into the well bore. The working principle is allowing the
certain size sand coming through the surface with crude oil but
keeping the bigger size sand being stopped outside to form sand
bridge, and thereby achieving the anti-sand purpose. This type of
product is commonly used to sand rock and carbonate reservoir, and
especially for horizontal wells.
Straight Types: straight slot, staggered slot, multiple staggered
slot, multiple straight slot.
Features:
1. Slots are made on base pipes with large ID/OD ratio.
2. High mechanical strength, high flexibility to allow adequate
bending, which makes it applicable in complicated well conditions,
and can be used in open-hole horizontal well completion for sand
control.
3. Low cost in manufacture and downhole installations.
4. Open hole area: 2%-6%
5. Base Pipe: J55, N80, P110
6. Laser cutting or mill cutting.
