Whakaahuatanga Hua

Ko te pane hurihuri API rarawe mō te taputapu keri kei roto i te taonga i runga i te utu iti rawa me te kounga pai mai i te wheketere Haina
Ko ngā taipitopito o te moka tricone IADC127 e whai ake nei:
1) Momo hiri hiri niho rino
2) te tiaki ine mō ngā hanganga ngohengohe
3) he iti te kaha pēhi, he teitei te kaha ki te keri.
Ko te kaha pēhanga he 0-35MAP me te 0-5000PSI.
Ngā Painga:
1) Kounga teitei - Tiwhikete mana ki te whakamahi i te API mana me te ISO.
2) Taputapu Ngaio - Te raina whakaputa maimoatanga wera matua o te ao
3) 20 tau o te hītori, kei te ao katoa te kiritaki

E whakahīhī ana a Far Eastern Drilling ki te hanga i tētahi whānuitanga o ngā Mīti Niho Mira tricone tuwhera-whanui. Ko ā mātou Mīti Niho Mira e kiia ana ko te mīti niho maitai tricone. E wātea ana i roto i ngā momo hanganga, pērā i te onepū, te dolomite me te granite, tae atu ki ngā hanganga ngohengohe pērā i te kirikiri, te uku me ngā moenga whero. Mā tā mātou mata-mārō tungsten carbide motuhake ka āwhina i te whakarato i te ātete nui ki te kakahu ine me te whakaiti i te wiri i roto i ngā hanganga pakeke. Mā te hoahoa Niho Mira a Thompson ka āwhina i ngā kai keri kia eke ki ngā reiti urunga teitei.
