Shrouded Wire-wrap Screen
The
SW shrouded wire-wrap screen has an additional bridge type shroud installed
outside of the wire-wrap layer which is point to point welded with optimized
structure strength. The bridge slots on the shroud could reduce direct flush
onto the screens, extending the working life of the wire-wrap layer inside. The
shroud could act as a filtering media as well, thus in the case that one of the
two layers fails, the screen could remain effective in sand control.
A
supporting ring with an OD larger than the screen itself is assembled to
minimize damages during running in horizontal or high-inclination wells.
The
SW shrouded wire-wrap screen is manufactured with 304 stainless steel with high
strength, resistance to corrosion and high temperature. It is especially
suitable for thermal recovery of heavy oil in horizontal or high-inclination
wells.
