Whakaahuatanga Hua

He mata keri toka API tricone rarawe kei roto i te taonga i runga i te utu whakaheke me te kounga pai rawa atu mai i te wheketere Haina.
Whakaahuatanga Moka:
IADC: 217 - Mata poroporo hiri niho rino me te tiaki ine mō ngā hanganga pakeke reo-waenga me te kaha pēhi teitei.
Kaha Whakapūmau:
0 - 35 MPA
0 - 5,000 PSI
Whakaahuatanga Whenua:
Ko ngā toka tino ngohengohe, kāore i te paparanga, kāore i te pai te kiato pērā i te uku me te kirikiri kirikiri kāore i te pai te kiato, te kōhatu kirikiri mārō, te tote, te gypsum, me ngā waro mārō.
Ka taea e Far Eastern Drilling te tuku i ngā mata wiri niho mira me ngā mata wiri tricone TCI o ngā rahi rerekē (mai i te 3” ki te 26”) me te nuinga o ngā waehere IADC.

E ai ki te rauemi tapahi, ka taea te wehewehe i ngā moka kōne e toru ki te moka TCI me te moka Niho Rino
Ko tētahi atu ingoa o ngā mata tricone niho rino ko te mata tricone niho mira nā te mea ka hangaia ngā niho e te mīhini mira, he tungsten carbide te mata o te kōne. He roa ake ngā niho o ngā mata tricone niho rino i ngā mata tricone TCI kia taea ai te keri i ngā hanganga ngohengohe i te ROP teitei.
I roto i ngā kaupapa keri hinu, ka taea e te ROP te eke ki te 30 mita ia hāora i roto i te keri wāhanga pāpaku.
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.

Ka whakarōpūhia anō ngā mata kōne roera i runga i ō rātou whāriki o roto. E toru ngā kōne hurihuri o ia mata, ā, ka hurihuri ia mea i runga i tōna ake tuaka i te wā e keri ana.
I te wā e mau ana ngā moka ki ngā taputapu keri, ka huri te paipa keri ki te taha matau, ā, ka huri ngā koeko roera ki te taha maui. Ka hurihia ia koeko roera ki tōna ake tuaka mā te āwhina o te peera. Waihoki, e toru ngā momo o ngā peera: Ngā moka peera tuwhera, Ngā moka peera hiri me ngā moka peera hautaka. Ko te moka IADC127 14 3/4" he peera hiri hautaka.

He tohunga wheketere a Far Eastern ki ngā mata keri, pērā i ngā mata keri tricone, ngā mata keri PDC, te whakatuwhera poka HDD, ngā taputapu tapahi turanga mō te puna wai, te papa hinu, te puna hau, te keri, te hanga, te geothermal, te keri aronga, me ngā mahi turanga raro whenua puta noa i te ao. Ko tā mātou kaupapa matua ko te utu keri iti rawa mō ia mita. Mā te kounga o Far Easter Drilling koe e āwhina ki te whakatutuki i ngā mea maha atu.
