Utu mō ngā mata wiri API tricone IADC216 4 5/8 inihi (118mm)
Whakaahuatanga Hua
E whakamahia whānuitia ana te mata tricone TCI 4 5/8" mō te keri puna wai, te tūhura, te poka pairati HDD, te whakatū pou turanga, he hoahoa poka jet pokapū tōna, nō reira ka taea hoki te whakamahi mō te keri tohanga whakamuri.
He hiri te peera, he roa ake te ora mahi i ngā porotaka peera tuwhera.
He kōhao kei waenganui o tēnei momo mata tricone niho rino, e tika ana mō te keri RC (keri Reverse Circulation).
Ka taea e te mata tricone IADC216 te keri i ngā hanganga pakari ake i te IADC126, ko te whiriwhiri i te IADC tika e ai ki te pakeke o ngā toka te taahiraa tuatahi o te keri whai hua teitei. He wheketere API whaimana a Far Eastern Drilling mō te mata roera tricone.
