FIELD: oil-and gas industry. ^ SUBSTANCE: device contains a tool for installation in a borehole, which has a hole for a fluid medium injection in to the well, a case, which at least partly covers the tool, for the tool eccentrically dislocation relatively to a longitudinal borehole axis, which has a section with a greater width in a radial direction, in a diapason of first angles around the tool's longitudinal axis. The tool's hole oriented under an angle lying-in the first diapason limit. ^ EFFECT: casing string damage decrease. ^ 16 cl, 6 dwg |
