Mata tricone hurihuri IADC537 6 1/4 inihi (159 mm)
Whakaahuatanga Hua
Ko ngā mata keri hurihuri tricone API hokohoko nui mai i te wheketere Haina hei whakamahi mā te puna hinu hohonu.
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.
Ko ngā Mata Tricone 6 1/4" he diameter noa mō te kōhao pairati HDD, e toru ngā pūwero jet taha o tēnei tauira, he pai ake te mahi waipēhi i te kōhao jet pokapū mō te whakakore i ngā maramara toka, inā koa mō te keri i ngā toka piri.
Kua arotauhia te matotoru me te teitei o ngā whakaurunga tungsten carbide kounga teitei kia eke ki te ROP (Rate of Penetration) pai rawa atu, kua hiritia te peera e te mowhiti-O Elastomer, ā, kua hipokina ngā ringa e ngā whakaurunga TC.
He tohunga a Far Eastern ki ngā mata wiri, pērā i ngā mata tricone, ngā mata PDC, te whakapuare poka HDD, me ngā taputapu tapahi roera turanga mō ngā momo mahi rerekē.
Hei wheketere mata keri matua i Haina, ko te whakanui ake i te roa o te mahi a te mata keri te whāinga. E ngana tonu ana mātou ki te whakapai ake i ngā mata me te tere uru teitei. Ko tā mātou whāinga he hoko i te kounga teitei me te utu iti rawa.
