A downhole tool () is provided for plugging a hole in a wall of a downhole tubular (). The tool has a tool housing () and a sting () arranged within the tool housing. The sting is moved in radially outward direction from the tool from a retracted position to an expanded position. A distal end of the sting plugs the hole in the wall of the downhole tubular. A spring blade () is arranged on the tool housing and in a trajectory of the sting. The sting () can extend from the tool housing through the spring blade (), when the sting is in expanded position, whereby the distal end of the sting is exposed at the outward facing side of the spring blade. The spring blade is configured to be pressed elastically towards the tool housing by the wall of the downhole tubular pushing against an outward facing surface of the spring blade.

Plugging tool for downhole tubulars and method for use thereof

A downhole tool, with an elongate tool housing that extends around a central longitudinal tool axis, houses a sting, a press device, and a bending arm. The sting is movable in a radially outward direction. The press device acts on the sting, to force the sting in the radially outward direction upon relative movement of the press device, in longitudinal direction, with respect to the sting whereby the sting may extend outside the tool housing. The sting is mounted on a distal end of the bending arm. At its proximal end the bending arm is longitudinally secured stationary relative to the tool housing. The sting and the distal end of the bending arm are movable in unison in a longitudinal-radial plane from the central longitudinal tool axis. The downhole tool can be used to perforate a wall of a downhole tubular arranged within a borehole in the Earth.
