Abstract

Oppfinnelsen vedrører fremgangsmåter for å undersøke brønner ved bruk av nukleær, magnetisk resonans. En oppfinnrisk fremgangsmåte består i å generere et statisk magnetfelt nær en brønn med hjelp av en magnet som er laget av et ledende, sjelden- jordartmateriale i form av et langstrakt parallellepiped som magnetiseres i en retning perpendikulær på en stor sideoverflate og langsgående akse derav. Magnetens bredde er minst 2 ganger så stor som den smale siden av nevnte parallellepiped. En radiofrekvensspole er anordnet på en ramme hvis diameter er lik eller høyere enn en diagonal av tverrsnittet av en magnet anordnet innenfor rammen. Spoleelementene er anordnet på plan som er parallelle med den langsgående aksen for magneten og vertikalt med hensyn til den mindre siden derav anordnet i symmetriske sektorer som er motsatt den store sideoverflaten av magneten. En kompenseringsenhet er anordnet langs de store sideoverflater av magneten parallelt med den langsgående akse derav.
