Ngā mata keri API IADC537 5 5/8″ (142.9mm)
Whakaahuatanga Hua
Ko ngā mata keri toka API tricone hokohoko nui mai i te wheketere o Haina e 2% te hekenga mō te rahinga nui.
Whakaahuatanga Moka:
IADC: 537 - Mata pere hiri TCI me te tiaki ine mō ngā hanganga ngohengohe ki waenga ngohengohe me te kaha pēhi iti.
Kaha Whakapūmau:
85 - 100 MPA
12,000 - 14,500 PSI
Whakaahuatanga Whenua:
Ngā toka mārō waenga, me ngā toka whakakoi pērā i te onepū me ngā rārangi o te kuata, te kōhatu mārō, te tiēre rānei, ngā konganuku hematite, ngā toka whakakoi mārō, kua pai te whakapiripiri pērā i: ngā onepū me te here kuata, ngā dolomite, ngā kirikiri kuata, te magma me ngā toka matotoru kua memeha.
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.
He mea tino nui te whiriwhiri i ngā mata keri kohatu tika i mua i te tīmatanga o te kaupapa.
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.
