Abstract

Anordning ved et borehullsarrangement hvor et foringsrør (11) for borehull (3) er tildannet av minst én foringsrørseksjon (1 la), og hvor det ved et nedihulls endeparti (1 lb) av foringsrøret (11) er anbrakt i det minste ett nedihullsverktøy (21), for eksempel et boreverktøy, kjennetegnet ved at foringsrøret (11) er forsynt med to eller flere rørløp (12, 13a, 13b) som hver for seg strekker seg sammenhengende gjennom en vesentlig del av foringsrørets (11) lengde og på fluidtett vis er atskilt fra tilstøtende rørløp (12, 13b, 13a) og fra et utvendig ringrom (14) som er avgrenset av rørets (11) utvendige mantelflate og en borehullsvegg (5a).Device in a downhole arrangement where a downhole casing (11) is formed by at least one casing section (1a), and at least one downhole tool (11) is provided at a downhole end portion (1lb) of the casing (11). 21), for example a drilling tool, characterized in that the casing (11) is provided with two or more pipe runs (12, 13a, 13b) which each extend continuously through a substantial part of the length of the casing (11) and in a fluid-tight manner. is separated from adjacent pipe runs (12, 13b, 13a) and from an outer annulus (14) defined by the outer jacket surface of the pipe (11) and a borehole wall (5a).
