  1. SYSTEMER OG FREMGANGSMÅDER TIL BORING MED KONTINUERLIG GENNESTRØMNING PATENTKRAV
    1. Kontinuerligt gennemstrømningsmellemstykke (200) til anvendelse med en borestreng, hvilket mellemstykke omfatter: et rørformet hus (205) med en langsgående boring derigennem og en åbning (201), der er dannet gennem en væg deraf; en kugleventil, der er placeret i boringen; og kendetegnet ved endvidere at omfatte: en kontraventil (1100), der er placeret i åbningen, og som omfatter: et legeme (1101) med en ydre væg, der er koblet til en del af husvæggen, der støder op til åbningen, og en indre væg, der er forbundet med den ydre væg med et bånd; en tallerkenventil (1102), der er placeret gennem en boring af den indre væg og som kan bevæges i forhold til legemet mellem en åben position og en lukket position; og en fjeder (1103), der forspænder tallerkenventilen mod den lukkede position, hvor tallerkenventilen bevæges til den åbne position som reaktion på et eksternt tryk, der overstiger det kombinerede tryk af et internt tryk fra husboringen og fjederen, og bevæges til den lukkede position som reaktion på, at det eksterne tryk er mindre end eller lig med det interne tryk.
  2. 2. Kontinuerligt strømningsmellemstykke (200) ifølge krav 1, hvor: tallerkenventilen (1102) går i indgreb med et sæde, der er dannet i en ende af legemet i den lukkede position, tallerkenventilen strækker sig ind i husboringen i den åbne position, hvorved fluid kan strømme gennem åbningen og ind i boringen.
  3. 3. Kontinuerligt gennemstrømningsmellemstykke (200) ifølge krav 1 eller 2, hvilket mellemstykke endvidere omfatter en kappe (1141), der er fastgjort til legemet og isolerer tallerkenventilen (1102) mod det eksterne tryk.
  4. 4. Kontinuerligt gennemstrømningsmellemstykke (200) ifølge krav 1, 2 eller 3, hvilket mellemstykke endvidere omfatter en fluidkobling (1120), der kan forbindes med legemet ved anvendelse af et afspæringsproplåse system.
  5. 5. Kontinuerligt gennemstrømningsmellemstykke (200) ifølge et hvilket som helst af de foregående krav, hvor det rørformede hus endvidere omfatter en første centraliserings- eller stabiliseringsanordning, der er placeret i umiddelbar nærhed af åbningen.
  6. 6. Fremgangsmåde til boring af et borehul, hvilken fremgangsmåde omfatter: boring af borehullet ved at indsprøjte borefluid i det øvre af en rørstreng, der er placeret i borehullet, ved en første hastighed og rotation af et borehoved, hvor: den rørformede streng omfatter: borehovedet placeret på bunden deraf, rørforbindelser, der er forbundet med hinanden, og det kontinuerlige gennemstrømningsmellemstykke ifølge krav 1, hvor kugleventilen er åben, og tallerkenventilen (1102) er i den lukkede position; bore fluidet forlader borehovedet og medtager boreaffald fra borehovedet, og boreaffaldet og borefluidet strømmer op til overfladen via et ringvolumen, der er defineret mellem borestrengen og borebrønden; og injektion af borefluid ind i åbningen (201) ved en anden strømningshastighed, mens rørstrengen tilføjes en rørforbindelse eller samlede rørforbindelser, hvorved tallerkenventilen åbnes, hvor indsprøjtning af borefluid i rørstrengen kontinuerligt opretholdes mellem boring og tilføjelse af rørforbindelsen eller samlede rørforbindelser til rørstrengen.
  7. 7. Fremgangsmåde ifølge krav 6, hvilken fremgangsmåde endvidere omfatter: at lade rørstrengen gå i indgreb med en roterende styreanordning (RCD), hvor en variabel drosselventil er placeret i en udgangsledning, der står i fluidforbindelse med RCD’en; og styring af trykket på tilbageføringer ved anvendelse af drosselventilen.
