FIELD: packers.
SUBSTANCE: invention relates to hydraulic packer. Hydraulic packer consists of sealing and injection modules joined by threaded joints for solution outlet. Sealing module consists of two end and one working section placed inside elastic membrane, fixed by fixing and pressure fittings on working section, on surface of which there are tapered run directed towards transverse filling holes. Working sections of the sealing modules have different diameters and are arranged so that the inner diameter of the working section of each lower sealing module is smaller than that of the working section of the above sealing module. Injection module is made in the form of hollow cylinder with internal thread in upper and lower parts. Number of transverse filling holes on working sections directly depends on length of sealing modules. Above installed sealing modules should have larger number of transverse filling holes in comparison with underlying ones, including at same length of these modules.
EFFECT: high tightness.
