Horizontal Well Screen (FGC-168)
FGС-168 horizontal well screen consists of a perforated base pipe with longitudinal slots, with a wire core made of the special stainless steel profiling wire of 2.5mm wrapped around its sleeve with a pitch of 0.15mm up to 0.35mm (as per customer specification) with an accuracy of ±0.03mm or ±0.05mm.
Impermeable sleeves are fitted every 350mm of the length of the screen under which plugs from duralumin are fitted. Due to high case impermeability, the washing can be performed through a shoe anchor (lower part of the casing) when filter is lowered down.
After installation, screens can be connected with the oil formation by drilling of previously installed plugs or by acid treatment.
The length of the screen section is 1620mm.
