Whakaahuatanga Hua

Ko ngā mata hurihuri toka API tricone i roto i te taonga mai i te wheketere Haina hei whakamahi mā ngā mīhini keri.
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 mata wiri TCI tricone hurihuri whakamuri 4 5/8 inihi (118mm) me te kōhao pupuhi pokapū.
1> He tukanga keri motuhake te Reverse Circulation, ka ngongohia te wai paru mai i te raro o te poka ki te whenua mā roto i te poka pokapū, ka mārama ake ngā maramara toka i te tere teitei ake i te rere noa.
2>He kōhao pupuhi kei waenganui o tēnei hoahoa o ngā mata tricone, ka taea te tohatoha i ngā maramara toka ki te whenua i roto i te paipa keri.
3>Ka whakamahia tonutia te tohanga whakamuri i te keri i ngā kirikiri, i ngā toka taratahi rānei, he teitei ake te ROP i te tohanga noa.
4>Ka taea te whakamahi i te mata kōhatu tricone me te kōhao pokapū i roto i te tohanga whakamuri me te tohanga noa.
Mā ā mātou raina whakaputa matatau, ngā paerewa o te ao (API Spec 7) me te rawaka o ngā rawa e tautoko ana i ngā kaupapa keri mō te tohatoha i ngā taputapu keri i runga i te ngaio me te tino tika.
Ā mātou mara ratonga: Hinu me te hau māori, HDD me te hanga, Tūhuratanga, Kerihanga, Puna wai, Pūngao waiariki, Tūāpapa, Taiao.
