Abstract

Oppfinnelsen vedrører en fremgangsmåte og et tilknyttet system for innstilling av nedihulls styretrykk. En fremgangsmåte for innstilling av et nedihulls styretrykk inkluderer trinnene å: installere trykkstyringssystem (24) med en trykkilde (28); kople en proksimal ende (26) av en ledning (22) til trykkilden (28) og en fjem ende til et brønnverktøy; kalibrere systemet ved påføring av et overfallstrykk til den proksimale enden, så føle et stabilisert trykk i den proksimale enden som resultat av overfallstrykket, og bestemme et matematisk forhold mellom overfallstrykket og det stabiliserte trykket. Et system for innstilling av et nedihulls styringstrykk inkluderer en trykkilde, en trykkbegrenser (30) og et grensesnitt for påføring av trykk til en maksimal ende av en styringsledning og et brønnverktøy (16) koplet til en fjem ende av styringsledningen. Brønnverktøyet blir operert som respons på et forhåndsbestemt stabilisert trykk oppnådd i den fjeme enden som respons på at et overfallstrykk blir påført den proksimale enden og at trykkbegrenseren begrenser påføring av trykk fra trykkilden til den proksimale enden til overfallstrykket.
