Mata keri whakarewa IADC637 14 3/4” (374.6mm) mō te poka hohonu
Whakaahuatanga Hua
Ngā mata keri tricone hiri whakarewa API rarawe me te utu whakaheke i roto i te taonga mai i te wheketere Haina mō te keri poka hohonu
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.
E ai ki te rauemi tapahi, ka taea te wehewehe i te mata thyrocne ki te mata TCI me te mata niho maitai. Ko te momo peera o te mata tricone he mea hiri ki te konganuku me te mea hiri ki te rapa.
Mō te keri poka hohonu rawa, ka tūtohu mātou i ngā mata tricone hiri-mata-konganuku mō te hohonu o te keri neke atu i te 1000 mita. Mō te keri poka kōhatu mārō me te keri poka tawhiti kore-awa e neke atu ana i te 300 mita te roa, ka tūtohu anō mātou i ngā mata tricone hiri-mata-konganuku.
Ko te TCI IADC637 he mea mō te hanga kohatu mārō. He mea tino nui te whiriwhiri i ngā mata keri kohatu tika 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.
