Abstract

Brønnverktøypakningselementsystemer som ikke krever et oppbakkingselement eller komponent innbefatter en spindel (30), en øvre bæredel (26), en nedre bæredel (28), et utkrageelement (22) og et rampeelement (24) anbrakt på spindelen. Utkrageelementet og rampeelementet er anbrakt på spindelen med en grensesnittvinkel mellom utkrageelementet og rampeelementet, grensesnittvinkelen er mindre enn 90 grader, fortrinnsvis i et område fra 40 grader til 60 grader, og mer foretrukket ved en vinkel større enn 45 grader. Når en aksial last er påført de øvre og nedre bæredeler, er utkrageelementet og rampeelementet tvunget utover og inn i en indre veggoverflate til et fôringsrør for å tette av fôringsrørboringen.
