DISINTEGRABLE TUBE ANCHOR SYSTEM AND METHOD OF ITS APPLICATION Russian patent published in 2016 - IPC E21B23/06 C22C1/05 

FIELD: mining.

SUBSTANCE: group of inventions relates to mining and can be used for disintegrable downhole tool. Disintegrable tube anchor system includes a frustoconical member; sleeve with at least one first surface radially varying in response to the longitudinal movement of the frustoconical member relative to the sleeve, wherein the first surface can interact with the wall of the structure; seal with at least one second radially varying surface and seat having a contact area that interacts with a seal with detachable plug thrust onto it. Frustoconical member, sleeve, seal and seat are disintegrable and independently contain a metal composite that has a cellular nanomatrix comprising a metallic nanomatrix material and a metal matrix disposed in the cellular nanomatrix. Isolation method comprises installation of disintegrable tube anchor system; radial variation of the sleeve to interact with the surface of the structure and radial variation of the seal to provide structure insulation.

EFFECT: technical result consists in improved efficiency of tool containing disintegrable tube anchor system.
