Abstract

Det omtales en sentraliseringsenhet som har et legeme med en indre overflate utstyrt med en friksjonsreduserende glider, vanligvis plassert i en ringformet utsparing på den indre overflaten til legemet til glideren, atskilt fra endene til legemet. Glideren kan utformes separat fra et legeme til sentraliseringsenheten og etterfølgende festes dertil på den indre overflaten slik at den er innrettet til å understøtte mellom den ytre overflaten til røret som skal sentraliseres og den indre overflaten til sentraliseringsenheten. Dette reduserer rotasjonsmoment overført mellom sentraliseringsenheten og røret, og medvirker ved manøvrering av rørstrengen inni den ønskede posisjonen i brønnen.
