Abstract

Et multigruppert selvstående stigerørsystem inkluderer ett eller flere mellomliggende oppdriftskamre konfigurert for å tilveiebringe en oppoverrettet løftekraft på strenger av tilknyttede stigerørsammenstillinger. De mellomliggende kamrene har enten en åpenbunnet eller lukket beholderkonstruksjon. Kamrene kan videre inkludere et hjelpeoppdriftsmateriale konstruert for enten å blandes med eller å inneholde trykksatte fluider injisert inn i kamrene. Det selvstående stigerørsystemet inkluderer videre en nedre stigerørsammenstilling festet til en primærbrønnboringsfikstur. Systemet inkluderer også en øvre stigerørsammenstilling og ett eller flere ytterligere oppdriftskamre anordnet i enten direkte eller indirekte kommunikasjon med hverandre, så vel som med bore-, produksjons- og leteboringsutstyr som påkrevd av de tilknyttede operasjoner.A multi-grouped standalone riser system includes one or more intermediate buoyancy chambers configured to provide an upward lifting force on strings of associated riser assemblies. The intermediate chambers have either an open bottom or closed container structure. The chambers may further include an auxiliary buoyancy material designed to either mix with or contain pressurized fluids injected into the chambers. The self-contained riser system further includes a lower riser assembly attached to a primary wellbore fixture. The system also includes an upper riser assembly and one or more additional buoyancy chambers arranged in either direct or indirect communication with each other, as well as with drilling, production and exploration drilling equipment as required by the associated operations.
