Ngā mata porotaka hurihuri IADC637 9 7/8” (250.8mm)
Whakaahuatanga Hua
Ngā mata keri tricone API TCI hokohoko nui me te utu whakaheke i roto i te taonga mai i te wheketere Haina mō ngā hanganga mārō.
Whakaahuatanga Moka:
IADC: 637 - Mata pere hiri TCI me te tiaki ine mō ngā hanganga pakeke waenga me te kaha pēhi teitei.
Kaha Whakapūmau:
100 - 150 MPA
14,500 - 23,000 PSI
Whakaahuatanga Whenua:
Ngā toka mārō, kua pai te whakapiripiri, pērā i: ngā kōhatu kōhatu mārō, ngā rārangi quarzite, ngā konganuku pyrite, ngā konganuku hematite, ngā konganuku magnetite, ngā konganuku chromium, ngā konganuku phosphorite me ngā granite.
Ka taea e Far Eastern Drilling te tuku i ngā mata TCI o ngā rahi rerekē (mai i te 3 3/8" ki te 26") me te nuinga o ngā waehere IADC katoa.
Ko te 9 7/8" he 250mm te whānui, ko te hononga miro he pine 6 5/8 noa e ai ki ngā whakaritenga API.
Ko te tikanga o te IADC537 he pai te mata hurihuri tricone mō te keri i ngā toka pakeke pērā i ngā rārangi quarzite, ngā granite, me ētahi atu. He hiri elastomer te peera hei roa ake te ora mahi.
He tino mārō te koranu whakauru tungsten carbide (TCI) hei keri i ngā toka mārō, ko te rekereke o ngā koeko me te tuara o te ringa kua whakaurua katoatia ki ngā niho tungsten carbide.
He rahi noa tēnei i roto i te mara keri, hei keri i te kōhao pupuhi. I roto i te keri keri, ko ngā tau tuatahi mō te waehere IADC ko te 6, 7, 8, ā, ko ngā tau tuatoru ko te 2 me te 5.
E ai ki ngā whakaritenga a te IADC mō te mata tricone, "2" te tikanga o te mata roera peera tuwhera paerewa, ā, ko te "5" te tikanga o te mata roera peera hiri me te tiaki ine.
I ētahi whenua, e whakamahia ana te 9 7/8" (250.8mm) hei keri i ngā puna wai me ngā puna waiariki. Ka hurihia te taputapu keri e te wai paru, kaua e te hau e pēhi ana.
Nō reira, mō ngā whakamahinga rerekē, me whiriwhiri tātou i ngā mata roera tricone tika.

He wheketere a Far Eastern e tohunga ana ki ngā mata keri, pērā i ngā mata tricone, ngā mata PDC, te whakatuwheratanga poka HDD, ngā taputapu tapahi turanga mō ngā momo tono maha. Kei roto i ngā tono ko te mara hinu, te hau māori, te tūhura whenua, te keri ahunga, te keri maina, te keri puna wai, te HDD, te hanga me te turanga...
Hei wheketere mata keri matua i Haina, ko te whakanui ake i te roa o te mahi a te mata keri ko tā mātou whāinga. E ngana tonu ana mātou ki te whakapai ake i ngā mata me ngā reiti urunga teitei. Ko tā mātou kaupapa matua he whakaiti i te utu o te keri-ia-mita. Ko tā mātou whāinga he hoko i te kounga teitei me te utu iti rawa.
