Abstract

Metoder og kontrollsystemer tilveiebringes for et borehull-boresystem (1000) med en aktiv differensialtrykkinnretning (APD-innretning) (1010) i fluidkommunikasjon med et returfluid. APD-innretningen (1010) skaper et differensialtrykk over innretningen (1010)og som reduserer trykket under eller nedhulls fra innretningen (1010). I utførelsesformer styrer en styreenhet (1002) APD-innretningen (1010) i sanntid via et dataoverføringssystem (1050) . I et arrangement inkluderer dataoverføringssystemet (1050) datakjeder ("data links") dannet av ledere (1060) assosiert med borestrengen (1040). Lederne (1060), som kan inkludere elektriske kabler og/eller fiberoptiske fiberbunter, kopler styreenheten (1002) til APD-innretningen (1010) og andre nedhulls verktøy som for eksempel følere (1030, 1032). I andre arrangementer kan datakjeden (1152, 1154) inkludere dataoverførings-stasjoner (1158) som anvender akustisk, EM og/eller RF signaler for overføring av data. I enda andre ytterligere utførelsesformer kan et slampulstelemetrisystem (1080) brukes i overføring av data og kommandosignaler.
