Abstract
Brønnhodekonstruksjon som er bestemt for installering i et bronnhodehus (10) med et innvendig monteringssete (14) og et innvendig forankringsspor (20) ovenfor monteringssetet, og som omfatter en rørhenger (16) med en innerkanal og en utvendig raonteringsskulder (18). Rørhengeren plasseres i huset med sin , monteringsskulder i anlegg mot husets monteringssete, for overforing til dette av belastninger fra rerhengeren. En utblåsningssikring (12) er fastgjort til den evre ende av huset. En lukkerdel (32) med en ytterseksjon (34) som innføres i rørhengerkanalen, innbefatter en utvendig, nedadrettet belastningsskulder (50), en splittet lagerring (52) nedenfor skulderen, og en hylse (54) som samvirker med splittringen, slik at når lukkerdelen trykkpåvirkes under testing av utblås- ningssikringen, vil hylsen tvinge splittringen utad til'fast, låsende inngrep med det innvendige spor i huset, hvorved testingstrykk-kreftene overføres fra lukkerseksjonens belast- ningsskulder til brønnhodehuset gjennom den splittede lagerring.Wellhead structure intended for installation in a wellhead housing (10) having an inner mounting seat (14) and an inner anchor groove (20) above the mounting site, and comprising a pipe hanger (16) having an inner channel and an outer mounting shoulder (18). The pipe hanger is placed in the housing with its, mounting shoulder in abutment against the housing mounting seat, for transfer to this by loads from the pipe hanger. A blowout fuse (12) is secured to the outer end of the housing. A shutter portion (32) having an outer section (34) inserted into the pipe hanger channel includes an outer, downwardly directed load shoulder (50), a split bearing ring (52) below the shoulder, and a sleeve (54) which cooperates with the split ring, such that when the shutter portion pressure is applied during testing of the blowout fuse, the sleeve will force the split outward to a fixed, locking engagement with the inner groove in the housing, whereby the test pressure forces are transferred from the shutter section's load shoulder to the wellhead housing through the split bearing ring.
