Abstract

En oppblåsbar pakningssammenstilling som benyttes ved servicearbeid i brønn og med en foring som bærer en normalt sammenfoldet, oppblåsbar pakningsenhet. Enheten innbefatter en indre elastomerblære omgitt av en forsterkning. For å styre formen av enheten under oppblåsning og derved å forhindre dannelsen av Z-folder i blæren, er dens aksielle stivhet fortrinnsvis øket i forhold til den periferiske eller ring- stivhet ved hjelp av anordninger slik som karbonfibre eller glassfiber-tape.
