Abstract

Brønnloggingsanordning med nukleær magnetisk resonans, samt en fremgangsmåte for bruk ved geofysisk undersøkelse av et borehull etter hvert som borehullet blir boret er anvist. Anordningen er koplet til en borkrone (36) for å følge den gjennom borehullet etter hvert som borehullet blir dannet. Anordningen omfatter en ettergivende, rørformet permanentmagnet (46) for å generere et statisk magnetisk felt l området av en del av borehullet nær Inntil anordningen, hvilket område innbefatter materialer som søkes å bli analysert, en antenne (48) montert på magneten og koplet til en tilhørende krets for å eksitere kjerner i materialene som søkes å bli analysert i området, og en mottaker koplet til antennen for å motta kjernemagnetlske resonansslgnaler fra de ekslterte kjerner og for å gi et utgangsslgnal som er indikerende for egenskapene til materialene som skal analyseres.
