Abstract

En forseglet, moduloppbygd brønnantenne (200) for måling av elektriske egenskaper l brønnborlngsflulder og brønnformasjoner. En antenne (200) Innbefatter et tynnvegget, kurveformet metallrør (202), som rommer, kveiler eller spoler av en lengde med ledende tråd (208). Ledningen 208 kan være Isolert med et Isolerende belegg, såvel som en fyller som ligger inne l røret (202). Røret (202) innbefatter et koplingsgap (204), for å muliggjøre kopling av elektromagnetisk energi gjennom røret til og fra den ledende tråd (208). Røret (202) har også en veggåpnlng (206), for feste av trådens (208) ender (208a-b) til en adapter-konnektor (210). Adapter-konnektoren (210) Innbefatter egnede organer for modulmesslg kopling til en elektrisk kabel, elektriske konnektorer eller annet elektrisk utstyr. Organene kan være anordnet for å sikre at slik forbindelse er motstandlg mot de høye trykk som ofte påtreffes nede i brønnen. I dette henseende kan røret også belegges med et tetningsmiddel-lag, for hermetisk å forsegle røret (202), koplingsgapet (204) og overgangen mellom adapter-konnektoren (210) og røret (202). Tetnlngsmlddel-laget kan innbefatte organer for å få til låsende inngrep med komplementært dimensjon- erte organer på et brønnverktøy.
