Abstract
A well tool device, which is for injecting an injection fluid through a hole in a well bore, includes a mandrel, an expandable sleeve provided circumferentially outside of the mandrel, a first and second expander, an injection fluid system, and a control fluid system. The first expander is for moving a first side of the expandable sleeve between a radially retracted state and a radially expanded state. The second expander is for moving a second side of the expandable sleeve between a radially retracted state and a radially expanded state. The injection fluid system includes an injection fluid line and a nozzle element. The nozzle element provides fluid communication between the injection fluid line and an outlet provided on the outside of the expandable sleeve. The control fluid system controls the fluid pressure in a first fluid compartment provided radially between the expandable sleeve and the mandrel.
