Abstract
A well tool device for transporting a heat generating mixture into a well pipe includes an upper connection section, a main housing section, and a sealing device. The main housing section includes a compartment for the heat generating mixture. The sealing device is provided below the main housing section. The sealing device includes a lower supporting element including a lower wedging surface; an upper wedging surface faced towards the lower wedging surface; and a sealing ring provided between the lower wedging surface and the upper wedging surface. The sealing element includes a plurality of thimble-shaped elements inserted into each other to form a torus. Relative axial movement between the lower wedging surface and the upper wedging surface in a direction towards each other provides radial expansion of the sealing element.
