Abstract

Brønnhullsverktøy for forankring og isolasjon av minst én sone i et brønnhull er beskrevet. Brønnhullsverktøyene omfatter en stamme som har en øvre ende, en nedre ende, en ytre veggoverflate og en gjennomgående, langsgående boring som har en akse. Ett eller flere ankre er anordnet gjennom den ytre veggoverflaten til stammen. Hvert av ankrene har en tilbaketrukket posisjon og en utstrukket posisjon. Et isolasjonselement er anordnet langs den ytre veggoverflaten til stammen. Isolasjonselementet kan dekke ankrene eller være anordnet over, under eller omkring ankrene. Kontakt mellom isolasjonselementet og den indre veggen i brønnhullet for å isolere i det minste én sone i brønnhullet, kan utføres ved å stikke hull på isolasjonselementet for å tillate brønnhullsfluid å komme i kontakt med et svellbart materiale som befinner seg inne i isolasjonselementet, eller ved å pumpe fluid inn i isolasjonselementet.
