FIELD: oil and gas production.
SUBSTANCE: expanded tubular item for use in geological structures consists of element of tubular shape with axis passing through it, of at least one spiral element made in wall of tubular element and of multitude of elongated perforated orifices. Also, the tubular element can be compressed to create energy content for expansion in the wall of the tubular shape element. According to one version of the invention the expandable tubular item can be made out of multitude of elongated parts arranged parallel to axis of the item. Each of multitude of elongated parts is fixed with at least one spiral element forming multitude of elongated perforations between them.
EFFECT: raised reliability of device operation and reduced time for its installation in well.
