  1. SYSTEMER OG FREMGANGSMÅDER TIL BORING MED KONTINUERLIG STRØMNING PATENTKRAV
    1. Fremgangsmåde til boring af et borehul (800), hvilken fremgangsmåde omfatter: boring af borehullet ved at indsprøjte borefluid (804f) i borehullet og ved rotation af et borehoved (803), der er forbundet med en bund af en første rørstreng, hvor den første rørstreng (802) omfatter: et borehoved, der er placeret på en bund deraf, rørforbindelser, der er forbundet med hinanden, en langsgående boring derigennem, en åbning gennem en væg deraf, og hvor borefluidet forlader borehovedet og medtager boreaffald fra borehovedet, og boreaffaldet og borefluidet strømmer op til overfladen; hvilken fremgangsmåde er kendetegnet ved indsprøjtning af borefluid i det første ringvolumen, der er dannet mellem den første rørstreng og en anden rørstreng, mens der tilføjes en rørforbindelse eller samlede rørforbindelser til den første rørstreng, hvor: borefluidet omledes ind i den åbning og gennem den første rørstreng via en tætning (805s), der er placeret i det første ringvolumen, og boreaffald og borefluid, der strømmer til overfladen, omledes ind i et andet ringvolumen eller en tredje rørstreng via tætningen.
  2. 2. Fremgangsmåde ifølge krav 1, hvor borefluidet (804f) sprøjtes ind i brøndboringen (800) via det øvre af en rørstreng.
  3. 3. Fremgangsmåde ifølge krav 1 eller 2, hvor: den første rørstreng (802) omfatter tætningen (805s), tætningen er retningsbestemt, og tætningen er frigjort fra den anden rørstreng under boring, og tætningen går i indgreb med den anden rørstreng som reaktion på indsprøjtning af borefluid (804f) i det første ringvolumen.
  4. 4. Fremgangsmåde ifølge krav 1, hvor borefluidet (804f) sprøjtes ind i brøndboringen (800) via det første ringvolumen.
  5. 5. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, hvor den første rørstreng (802) endvidere omfatter: en svømmerventil (805f), der er placeret i boringen, og en kontraventil (805c), der er placeret i åbningen.
  6. 6. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, hvor den første rørstreng (802) endvidere omfatter: en bøsning, der er placeret omkring én af rørforbindelseme under åbningen, et leje, der er placeret mellem bøsningen og den ene rørforbindelse, således at bøsningen kan rotere i forhold til den ene rørforbindelse, hvor tætningen (805s) er placeret omkring bøsningen.
  7. 7. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, hvor den anden rørstreng er en forbindelsesrørstreng (80lt).
  8. 8. Fremgangsmåde ifølge et hvilket som helst af kravene 1 til 6, hvor den anden rørstreng er et stigror (801r).
  9. 9. Fremgangsmåde ifølge krav 8, hvor tætningen (805s) er en del af en roterende styreanordning (821), der er forbundet med et undersøisk brøndhoved.
