Abstract
En brønn med et vertikalt foringsrør (13) med et vindu (14) og en horisontalbrønn som kommuniserer med vinduet og som kan oppvise et foringsrør (18). En vindusmontasje (31) innrettet med vinduet (14) har respektive passasjer for første (51) og andre (52) produksjonsrør, og oppviser ei konkav overflate (36) for avbøyning av det første produksjonsrøret ut og inn i horisontalbrønnen. Passasjen for det andre produksjonsrøret har en del som er avskrådd i en svært liten vinkel med hensyn til ei vertikal senterlinje i det vertikale foringsrøret. Mens det første produksjonsrøret kjøres inn i det vertikale foringsrøret er røret frigjørbart forbundet med et lokaliseringsorgan (126) med hjelp av et koplingsorgan (176). Etter at lokaliseringsorganet har bevirket rotasjonsmessig orientering, blir koplingsorganet (176) frigjort for derved å tillate det første produksjonsrøret (51) å beveges forbi samme uten skade. Et pakningsarrangement (56) på det første produksjonsrøret (51) er dekket med ei beskyttelseshylse (147) etter innføring i sidebrønnen.
