Abstract

Et system og en fremgangsmåte i samsvar med oppfinnelsen kommuniserer med fjerntliggende styrbare nedihullsverktøy i et borehull ved en boreinstallasjon. På overflaten blir trykkimpulser med høy energi dirigert inn i rørledningen eller ringrommet, eller begge deler, ved et nivå som er tilstrekkelig til å forplante impulsen gjennom en grenseflate mellom soner med meget forskjellige impedanser, slik som en øvre gass-sone og et nedre nivå med mobile fluidmedier som strekker seg ned til det ønskede sted nede i borehullet. Trykkimpulsen som tilveiebringes ved retningsmessig ledning langs den langsgående begrensede bane av en trykkimpuls som til å begynne med har skarpe forflanke- og bakflanke-kanter, når stedet nede i borehullet som fysiske forstyrrelser som danner et skjelnbart mønster som kan detekteres av én eller flere energireagerende transdusere. Med kombinasjoner av disse signalene kan én av et antall separate styreinnretninger fjernstyres. Systemet unngår behovet for fysiske eller elektriske forbindelser og reduserer samtidig sannsynligheten for utidig operasjon i sterk grad.
