Abstract

Fremgangsmåte til bestemmelse av elektrisk anisotropi i en kjerneprøve (11) fra en underjordisk formasjon. En sylindrisk kjerneprøve (11) fra en underjordisk formasjon er anbragt i en hylse (10) under et sammen- holdende trykk. Minst en elektrodesats (A) går gjennom hylsen og får kontakt med kjerneprøven (11). Satsen (A) står i et plan perpendikulært på kjerneprøven (11) og har et like antall elektroder (Ai-A24) som er Jevnt fort elt rundt hylsen (10). En strøm føres gjennom kjerneprøven (11) og spenninger måles over hvert par elektroder (Aj-A^' etc.) som står 180' fra hverandre rundt hylsen. Slike målinger benyttes til å påvise den radielle retning for mulig elektrisk anisotropi i kjerneprøven (11), særlig under varierende betingelser for fluidummetningen.Method for determining electrical anisotropy in a core sample (11) from an underground formation. A cylindrical core specimen (11) from an underground formation is placed in a sleeve (10) under a coherent pressure. At least one electrode kit (A) passes through the sleeve and contacts the core sample (11). The kit (A) stands in a plane perpendicular to the core sample (11) and has an equal number of electrodes (Ai-A24) which are evenly distributed around the sleeve (10). A current is passed through the core sample (11) and voltages are measured across each pair of electrodes (Aj-A ^ 'etc.) standing 180' apart around the sleeve. Such measurements are used to detect the radial direction of possible electrical anisotropy in the core sample (11), especially under varying conditions of fluid saturation.
