Abstract

FIELD: petroleum and gas extracting industry. SUBSTANCE: the well screen with suspension flow channels enclosed in it uses supporting rods running in the axial direction of this screen and spaced at preset intervals on the screen external side surface, wire wound on the external periphery of the supporting rods to form slots of the preset width, one or more gravel-containing suspension flow channels made on the inner side of the wire and running in the screen axial direction, holes for communication of the flow channels with the screen external surface. The screen can be lowered and lifted through the well smoothly without any interference for the suspension flow channels on the well side; screen mounting may be made easier. EFFECT: improved design.
