Abstract

A device for a borehole arrangement, in which a casing (11) for a borehole (3) is formed of at least one casing section (11a), and in which there is placed at a downhole end portion (11b) of the casing (11) at least one downhole tool (21), for example a drilling tool, characterized in that the casing (11) is provided with two or more pipe bores (12, 13a, 13b), each separately extending continuously through a substantial part of the length of the casing (11) and being separated in a fluid-tight manner from adjacent pipe bores (12, 13b, 13a) and from an external annulus (14) defined by the external mantle surface of the pipe (11) and a borehole wall (5a).
