Fa'atau oloa si'isi'i API suau'u tricone papa vili i totonu o fa'atauga ma tau fa'aitiitiga mai Saina falegaosimea
Far Eastern Drilling e mafai ona ofoina atu TCI tricone bits ma nifo uamea tricone bits i ituaiga eseese (mai le 3” i le 26”) matele ole IADC Codes.
IADC: 237 o u'amea nifo tusi talaaga faamaufaailogaina tauaveina bit ma gauge puipuiga mo alafua i tulaga faigata feololo ma maualuga compressive strength.The compressive malosi o 20-40MPA ma 3000-6000PSI / 20 - 40 MPA / 3,000 - 6,000 PSI.
IADC237 triocne bits o le a faʻaaogaina mo maʻa oneone o loʻo i ai faʻailoga o le quartz, maʻa maʻaʻa poʻo le sieri, dolomites tioata, oa hematite, ma shales malo.

O le a matou faʻasoa faʻamatalaga e uiga i le auala e filifili saʻo tricone bits?
A. E 2 ituaiga o triocne bits e fa'atatau i nifo.
1) Uamea ttooth tricone bits (IADC1**,IADC2**,IADC3**)
2) TCI tricone bits (IADC4**,IADC5**,IADC6**,IADC7**,IADC8**)
B.E 4 ituaiga o tricone bits e faʻavae i luga o le faʻamomoli ituaiga.
1) Fa'amauina o talatala (IADC**6,IADC**7)
2) Ave ta'avale (IADC**4,IADC**5)
3) Tatala fa'amau (IADC**1)
4) Ave le ea (IADC**2,IADC**3)
C O nisi fa'amatalaga:
1) E sili atu ona lelei le fa'atulagaina o le uamea tricone bit, eg palapala.
2) Fa'atonuga faigata e sili atu ona filifili TCI tricone bit, fa'ata'ita'iga ma'a.
3) O lo'o fa'asolo, fa'amau fa'amaufa'ailoga e tele lava ina fa'aaogaina i galuega e viliina vai lelei.
4) Tatala paʻu, faʻafefe o le ea, faʻapipiʻi taʻavale e tele lava ina faʻaaogaina i galuega faʻapitoa.
5) Filifili le tricone bit e tusa ai ma le malosi faʻamalosi
