Fa'amatalaga o oloa
Fa'atau oloa siisii API fa'apitoa tricone rock bit i fa'atauga e fa'atatau i upusii aupito maualalo ma uiga lelei mo le vili loloto.
1) Drill Bit Connection faia e tusa ai ma tulaga API.
2) E mafai ona matou fetuutuunai le lapopoa e tusa ai ma lau rig.
3) O le taunuuga sili e mafai ona maua e ala i le faʻaaogaina o le sila-nifo uʻamea i le stratum vaivai. Afai o le faʻaaogaina i le faigata, e fautuaina le TCI tricone bit.
4) Fa'amaonia le tipiina o fausaga ma fa'ata'ita'iga o lo'o fa'aauau pea ona tu'uina atu se tulaga maualuga o le fa'atinoga ma le fa'amaoni.
5) O masini fa'alelei fa'alelei e maua ai le ROP fa'ateleina e ala i le aveeseina lelei o tipi ma fa'amautinoa le fa'aogaina o ma'a fou i luga o suiga uma o le fausaga.
