An arrangement for plugging a wellbore (11) in an underground formation (1), in which a non-rotatable tool string (6) extends from a well-plugging module (5) arranged over a wellhead (3) down to a plugging zone (112) in the wellbore (11), the well-plugging module (5) including a feeding apparatus (52) for the tool string (6) which includes at least one line groove (613, 614) arranged to receive one or more lines (55, 55a) extending from an energy-supply unit (56) via a first line reel (53) to a tool module (7) arranged in a lower end portion (62) of the tool string (6); and the tool module (7) including at least one of a tool taken from a group including a milling tool (71) with a radially expandable, rotatable milling head (711), a tool (72) for setting a boundary plug (8) in or near the plugging zone (112), and a cementing head (73), and at least one sensor (74, 75, 76) which is connected to a control unit (57). |
