Abstract

SAMMENDRAG Et ekspertsystem er innbefattet i en brønnhullsprosessor innrettet for å samle inn og behandle NMR-data nede i et borehull i sanntid. Brønnhullsprosessoren styrer innsamlingen av NMR-dataene basert i det minste delvis på instruksjoner sendt ned i borehullet fra et overflatested og i det minste delvis på evaluering av brønnhullstilstander av ekspertsystemet. Brønnhullstilstandene innbefatter boreoperasjonsforhold (innbefattende bevegelsessensorer) samt litologi og fluidinnhold i formasjonen fremskaffet fra andre MWD-data. Ventetiden, antall ekko, antall repetisjoner av en ekkosekvens, interekko-tid, båndbredden og formen til vippe- og refokuserings-pulsene kan endres dynamisk.
