Abstract

Et styresystem for drift av en brønnsikringsventil er omtalt. Styresystemet benytter et trykksatt gasskammer, såvel som en sleideventil som er forbundet til hoved- fluidtrykktilførselen fra overflaten. Sleideventilen er forbundet til det gassholdige kammeret såvel som til et barrierestempel. Som et resultat av arrangementet, re- sulterer lekkasjer mellom nedstrømssiden av driftsstemplet og sleideventilen i en reetablering av trykkbalansen på driftssystemet som medfører at brønnsikrings- ventilen lukker seg. 1 tillegg, i tilfelle av tap av gassholdig trykk, oppstår den sam- me trykkbalanserende effekten på driftsstemplet, som sørger for at brønnsikrings- ventilen går til en lukket posisjon. Utformingen av styresystemet, som innbefatter et gassholdig kammer, sørger for fråkopling av den hydrauliske fluidtilførselen før den forhåndsbestemte dybden nås for å tilrettelegge forbindelsen av en rørhenger.
