1.Slotted tube is in various ways on the petroleum casing or tubing cutting out more than a certain specifications
of the longitudinal or helical inline and staggered slot.
2.it is using special ultra-thin cutting plate and beam cutting , the slot width is 0.2 to 0.5 mm. Seam cross section
is rectangular, trapezoidal (trapezoid Angle of 3-8 degrees) and form (hole) and so on , there are many kinds
of form, could guarantee permeability is 0.5% - 10%, the arrangement of aperture according to user requirements for processing.
1. The slotted pipe is suitable for the sand particle size is greater than 0.3 mm of sand sand control well.
2. Cutting edge verticality, trimming smooth, without burr, cutting evenly.
3. The flow area is large, 27/8 "screen 300 slot / 1.5 m, 2.4 times larger than pipe flow area of the same specification.
4. The overall anticorrosive processing, improved the sieve tube corrosion resistance and wear resistance, can prolong the downhole working life.
5. The slotted tube adopts J55 and N80 oil casing processing, high strength, not easy to deformation.
6. The size is big, easy to pipe operation
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.
