Abstract

Trykkbalanserte nedihullskoplinger. Et brønnsystem (1 0) inkluderer et brønnverktøy (14, 16, 18), en kanalsammenstilling (24) koplet til brønnverktøyet (14, 16, 18), hvilken kanalsammenstilling (24) inkluderer en kanal (30) og en ledning (46) posisjonert inne i kanelen (30), i hvilken ledning (46) er koplet til brønnverktøyet (14, 16, 18) for operasjon av brønnverktøyet (14, 16, 18), og en innretning (34) for utlikning av trykk mellom en innside og en utside av kanalen (30), hvilken innretning (34) er posisjonert nedihulls. En fremgangsmåte for isolering av en ledning i en undergrunnsbrønn fra brønnfluider i brønnen inkluderer trinnene; og kople en kanalsammenstilling til en innretning for utlikning av trykk mellom en innside og en utside av kanalsammenstillingen, idet kanalsammenstillingen inkluderer en ledning installert i en kanal; og å posisjonere kanalsammenstillingen og trykkutlikningsinnretningen i brønnen. 104, 46g 86 52 · 4 · 6 46f ge 92 102
