Abstract

En brønnloggingskabel omfatter første lederelementer, hvert bestående av en ståltråd omgitt av kobbertråder og dekket av et elektrisk isolerende materiale, og minst et annet lederelement som innbefatt- er minst en optisk fiber innesluttet i et metallrør, ledende kledning forbundet med innerveggen av røret, og hvor røret er dekket av det elektrisk ledende material- et. De første elementer og det minst ene annet element er anordnet i en sentral bunt. Det annet lederelement er posisjo- nert i bunten slik at det er spiralviklet omkring buntens sentrale akse. Bunten er omgitt av armeringstråder som er spiral- viklet på utsiden av bunten.A well logging cable comprises first conductor elements, each consisting of a steel wire surrounded by copper wires and covered by an electrically insulating material, and at least one other conductor element including at least one optical fiber enclosed in a metal tube, conductive cladding connected to the inner wall of the tube, and wherein the pipe is covered by the electrically conductive material. The first elements and the at least one other element are arranged in a central bundle. The second guide element is positioned in the bundle so that it is coiled around the central axis of the bundle. The bundle is surrounded by reinforcing threads spirally wound on the outside of the bundle.
