Abstract

Et system for måling under boring har typisk en metallrørledning som strekker seg i undergrunnen, forbundet til en antenne. Metallrørledningen og antennen er begge forbundet til en type nedihullsutstyr. Antennen sender eller mottar signaler til/fra en transceiver som er lokalisert på overflaten, og transceiveren er forbundet til metallrørledningen og til grunnen. Systemet er forbedret ved at en flerhet av seksjoner av kablet borerør er sammenføyd for å danne en seksjon hvor antennen er integrert med metallrørledningen. En ende av seksjonen av kablet borerør er forbundet til nedihullsutstyret, og en annen ende er forbundet til en konvensjonell metallrørledning.
