Pītiti wiri hurihuri IADC617 12 1/4 inihi (311mm)
Whakaahuatanga Hua
He mea hokomaha te wiri pātene o ngā koeko hurihuri API me te peera hiri whakarewa i roto i te taonga mai i te kaiwhakarato Haina
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 mātou te tuku atu i ngā momo rahi o ngā moka TCI (mai i te 3 3/8" ki te 26") me te nuinga o ngā waehere IADC.
E ai ki te rauemi tapahi, ka taea te wehewehe i te mata tirocne ki te mata TCI me te mata niho maitai.
Ko te TCI IADC617 he mea mō te hanganga mārō waenga. He mea nui te whiriwhiri i ngā mata keri tika mō ngā toka i mua i te tīmatanga o te kaupapa.
Ka taea e te pakeke o ngā toka te ngohengohe, te pakeke waenga, te pakeke tino pakeke rānei, ka rerekē pea te pakeke o tētahi momo toka, hei tauira, he toka kōhatu, he toka onepū, he toka kōhatu ngohengohe, he toka kōhatu waenga, he toka kōhatu pakeke hoki te kirikiri, he toka kōhatu waenga, he toka onepū pakeke hoki, me ētahi atu.
I roto i te kaupapa keri, he 15 tau a Far Eastern me te neke atu i te 30 whenua o te wheako ratonga ki te whakarato i ngā mata keri me ngā wairua keri matatau mō ngā tono maha. Kei roto i ngā tono ko te mara hinu, te hau māori, te tūhura whenua, te keri awa, te keri, te keri puna wai, te HDD, te hanga, me te turanga. Ka taea te whakarite i ngā momo mata keri kia rite ki ngā hanganga toka rerekē nā te mea kei a mātou ake wheketere tohu API me ISO mō ngā mata keri. Ka taea e mātou te whakarato i te otinga a tā mātou miihini ina taea e koe te whakarato i ngā āhuatanga motuhake, pēnei i te pakeke o ngā toka, ngā momo taputapu keri, te tere hurihuri, te taumaha o te mata me te taipana. Ka āwhina hoki mātou ki te kimi i ngā mata keri e tika ana i muri i tō whakamōhio mai ki a mātou mō te keri puna poutū, te keri whakapae rānei, te keri puna hinu, te keri Kore-Keri, te whakatō turanga rānei.
Me pēhea te tuku ota?
1>Kōrero mai ki a mātou ngā taipitopito o ngā mahi keri, tae atu ki te hohonu, te roa, te pakeke o ngā toka, ngā mōhiohio mō ngā taputapu keri, me ētahi atu.
2>Te whānui o ngā mata wiri tricone me te waehere IADC.
3>Te rahinga o te ota me te wā tuku e tumanakohia ana.

He tohunga a Far Eastern ki ngā mīhini keri, pērā i ngā mīhini tricone, ngā mīhini PDC, te whakatuwhera poka HDD, ngā mīhini tapahi turanga mō ngā momo mahi maha. Kei roto i ngā mahi ko te mara hinu, te hau māori, te tūhura whenua, te keri ahunga, te keri, 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.
