Tool and a method for at least one of gripping, expanding, and penetrating a wall of a bore

A tool for at least one of gripping, expanding, and penetrating a wall of a bore, the tool comprising a first tool part and a second tool part arranged axially movable relative to each other, wherein the first tool part comprises a solid wedge, whereas the second tool part comprises at least one wedge arm;

• wherein the first and second tool parts are aligned so that a tip of the solid wedge is pointed towards a tip of the at least one wedge arm,
• wherein the first tool part also comprises at least one influencing portion configured to be radially movable upon contact with the at least one wedge arm of the second tool part,
• wherein, when the tool is activated and the first and second tool parts are forced against each other, the at least one wedge arm is configured to be moved axially along the solid wedge so as to be forced radially outwards and thus push the at least one influencing portion radially outwards for at least one of gripping, expanding, and penetrating the wall of the bore,
• wherein the bore is a pipe;
• and wherein the at least one influencing portion is configured for penetrating the wall of the pipe, and
• wherein the at least one influencing portion is provided with an aperture being in fluid communication with a conduit configured for receiving an injection fluid from a source of injection fluid.

A method of at least one of gripping, expanding, and penetrating a wall of a bore, the method comprising:

• providing a tool for at least one of gripping, expanding, and penetrating a wall of a bore, the tool comprising:
• a first tool part and a second tool part arranged axially movable relative to each other, wherein the first tool part comprises a solid wedge, whereas the second tool part comprises at least one wedge arm;
• wherein the first and second tool parts are aligned so that a tip of the solid wedge is pointed towards a tip of the at least one wedge arm,
• wherein the first tool part also comprises at least one influencing portion configured to be radially movable upon contact with the at least one wedge arm of the second tool part,
• wherein, when the tool is activated and the first and second tool parts are forced against each other, the at least one wedge arm is configured to be moved axially along the solid wedge so as to be forced radially outwards and thus push the at least one influencing portion radially outwards for at least one of gripping, expanding, and penetrating the wall of the bore,
• connecting the tool to a control device configured for operating the tool;
• running the tool into the bore and down to a desired location within the bore, wherein the bore is a pipe, and wherein the tool is provided with an influencing portion provided with an aperture being in fluid communication with a conduit configured for receiving an injection fluid from a source of injection fluid;
• activating the tool for at least one of gripping, expanding, and penetrating the wall of the bore;
• and
• injecting said injection fluid into an annulus defined between an outside of the pipe and a bore surrounding the pipe.
