Abstract

Innretninger og fremgangsmåter for setting av en pakning inne i en brønnboring med liten merkbar reduksjon av det anvendelige areal i brønnboringen. Det ytre fôringsrør eller forlengningsrør i brønnboringen inneholder en eller flere integrerte fôringsrørkoplingsskjøter som har et kammerparti med økt diameter. Et pakningselement med stor boring bæres inne i kammerpartiet med økt diameter. Pakningselementet kan selektivt aktueres for å danne en tetning mot et indre rørorgan. Fordi pakningselementet er lokalisert inne i kammerpartiet i fôringsrørkoplingen, kan pakningen settes samtidig som man sparer anvendelig tverrsnittsareal inne i fôringsrøret. 1
