Filter FSEL
Filter FSESH
Filter FSEP
Well filters are used for cleaning fluids and gases from
sand and mechanical impurity. Filter is set as a part of
casing production string in the area of productive ledge of
oil and gas wells.
Filter FSEL (net-shaped filter, laminar screen) consists
of casing pipe with holes which are situated in the area of
filtering part. Each hole is muffled by cut plugs and is
placed one by one with the gap of 15 degrees. Internal
drainage net, filtering net, external drainage net and
perforated screen are placed concentric relating to the
well.
The main difference of FSEP (net-shaped filter, cuttingout screen) and FSESH (net-shaped filter, pressed screen)
from FSEL is in material of the screen. The screens of
FSEP and FSESH are made from cutting-out and
stretching or pressed metal plate.

Comparison of perforated and cutting-out stretching plates
Cutting-out stretching plate is produced in accordance with TY 36.26.11-5-89. Breakthrough is cut and
stretched from stainless steel. Its thickness is 0,5-1,0 mm.
Main advantage: Cutting-out stretching plate has higher rate of flow in comparison with perforated plate.
Perforated plate
Cutting-out stretching plate
Comparison of passing ability through horizontal well bore
Filter produced from perforated or cutting-out stretching plate
Filter moves easily along the lower part of horizontal bore
Slotted filter
Pressed slotted filter
Such filter constructions hooks the lower part of horizontal bore. It can result in
complication of lowering or in destruction of filter construction
Filtration of nonspherical-shaped parts by slotted and net filter
Net filtering element provides effective filtration in mutually transverse surfaces
Advantages of above-listed filters

Safe protection from sand

Long effective period of safe protection from sand without obstruction

High stability from damages and deformations

High productivity and low resistance against fluid flow

Immune to corrosion caused by acid, alkali and salt

Can be easily moved for long distances in horizontal part of the well

Large area of filtration

Controlled accuracy of filtration

Very safe construction

Using filter with plugs while pressure is high (up to 10 Mpa)
Centralizers
Shear test of aluminium and plastic plugs
