Whakaahuatanga Hua

He mea nui te whiriwhiri i te tricone tika i te wā e keri ana. Ko te IADC537 he mata hiri TCI me te tiaki ine mō ngā hanganga ngohengohe ki te ngawari waenga me te kaha pēhi iti.
Kāore pea e ōrite te pakeke o ngā toka, pērā i te ngohengohe, te waenga me te pakeke, te tino pakeke rānei. Kāore pea hoki e ōrite te pakeke o tētahi momo toka, hei tauira, he kōhatu kirikiri, he kōhatu kirikiri ngohengohe, he kōhatu kirikiri waenga me te kōhatu kirikiri pakeke, he kōhatu kirikiri waenga me te kōhatu kirikiri pakeke, me ētahi atu.
E 15 tau te roa o te wheako ratonga a Far Eastern, ā, neke atu i te 30 whenua te roa o te wheako ki te whakarato i ngā mata keri me ngā wairua keri matatau mō ngā momo tono maha. Kei roto i ngā tono ko te mara hinu, te hau māori, te tūhura whenua, te keri awa, te keri puna wai. Ka taea te whakarite i ngā momo mata keri kia rite ki ngā hanganga toka rerekē nā te mea kei a mātou ake wheketere API me te ISO mō ngā mata keri tricone. Ka taea e mātou te whakarato i te otinga a te 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 taea e Far Eastern Drilling te tuku i ngā mata tricone o ngā rahi rerekē (mai i te 3" ki te 26") mete nuinga o ngā waehere IADC.
