Abstract

SAMMENDRAG Beskrivelsen omhandler en ferrittkjerneantenne basert på trykt kretskort. Sporene (54, 58) på kretskortene (50, 52) danner vindinger for antennen, på forskjellige lag (62A, 62B og 62C) av trykte kretskort holder en ferrittkjerne (74) for vindingene på plass. Beskrivelsen angir videre bruk av en slik ferrittkjerneantenne basert på trykt kretskort i et nedihulls elektromagnetisk resistivitetsverktøy, slik at asimutal-følsomme resistivitetsavlesinger kan tas, og borehullsavbildning kan utføres, selv i oljebaserte utboringsfluider.
