Abstract
An apparatus for severing a conduit in the borehole includes a combustible fuel; a nozzle section comprising a cavity with apertures providing passages from the cavity to outside the apparatus; a movable swirl generator located between the combustible fuel and the nozzle section, the swirl generator comprising a piston and a plurality of helical vanes, the piston located initially above the apertures; and an activation device for igniting the combustible fuel for creating a matrix of combustion products that pass between and/or along the helical vanes and move the swirl generator in the cavity so that the piston is moved below the apertures for passage of the matrix of combustion products into the cavity and out of the apertures. The helical vanes rotate the matrix of combustion products and direct the rotating matrix of combustion products radially through of the apertures for cutting the conduit.
