Abstract

Det er omtalt et nedhulls elektromagnetisk telemetrissystem med en økt dataoverføringshastighet. l en viss utførelse brukes et PSK-dataoverføringssystem for å overføre data ved hjelp av et nedhulls elektromagnetisk telemetrisystem for anvendelser ved måling-under-utboring (MWD). Slike MWD-anvendelser lider av dataoverføringshastigheter som ikke er vel egnet for de stadig økende datamengder som skal overføres. En fremgangsmåte for å øke dataoverføringshastigheten omfatter økning av bærefrekvensen, men dette kan forårsake uønsket signalsvekking og forvrengning. Svekking av bærefrekvensen medfører omvendt at det oppnås et sterkere signal, men med risiko for uønsket signaldannelse, spesielt ved bredbåndssignaler. Det er angitt en utledning som forutsier at frekvensen faktisk kan senkes samtidig som antallet fasetilstander kan økes for på denne måte å oppnå en høyere dataoverføringshastighet, uten at derved båndbredden påvirkes. Det system og den fremgangsmåte som er omtalt vil med fordel kunne frembringe et robust, laveffekts elektromagnetisk telemetrisystem med en økt dataoverføringshastighet.
