Abstract

Et trykk-kjerneløp (10) som innbefatter et indre rør (100) som inneholder en ikke-invaderende gel for innkapsling av en kjerneprøve (51) er vist. En "antivlrvlende" kjerneborkrone blir benyttet, og borkronen og en indre rørledesko (246) er utformet og anordnet for å hindre skade fra borefluldet på kjernen. Et spesielt høyviskøst kjerneprøvetakingsfluid blir benyttet i kjerneborlngsoperasjonen. Når den innkapsle- de, trykksatte kjerneprøve (51) bringes til overflaten ventileres trykket bort og kjerneprøvens (51) kjemiske og mekaniske integritet blir i hovedsak preservert av gelen.
