Stainless Steel Slotted Liner Screen Sieve Pipe For Sand Control Well

Reliable Slotted Liner for Horizontal Completion Well

Slotted liner is a robust and effective device for sand control in the horizontal completion wells and other thermal heavy oil recovery. Its excellent properties in withstanding installation loads and operation loads make it premier choice.

Slotted liners are manufactured by laser cutting process without contact operation. This process can effectively avoid undesirable factors which will cause the deformation of the base pipe. Laser cutting process uses windows interface for easy operation and accurate calculation.

Slotted Liner Patterns: straight pattern, staggered pattern, gang pattern are applied. Each has its own characteristics.

Slotted liner geometry consists of slot length, slot width, slot density and slot distribution. All these parameters can be bespoken to achieve the required open area. Fox example, multiple staggered pattern or gang pattern significantly increase the open area compared with single cut pattern.

Slotted Geometry

Slotted shapes are classified into two types: straight cut slot and keystone cut slot. Compared with straight slot, keystone slot has higher resistance against plugging for its inter size is larger than the surface size. Once the sand entering the keystone slot, the possibility of clogging will drop sharply.
