API fa'amau vili papa ma'a IADC537 8 3/4″(222.2mm) fa'atasi ai ma tau fa'aitiitiga
Fa'amatalaga o oloa
Fa'atau oloa si'isi'i API fa'amau ma'a vili vili bits IADC537 8 3/4" mo le loloto loloto i le fa'asoa mai Saina falegaosimea
Vaega Autu
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 e la'u mai i se tulaga faigata, e fautuaina le TCI tricone bitis.
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 faʻaleleia lelei e maua ai le ROP faʻateleina e ala i le aveeseina lelei o tipi ma faʻamautinoa le faʻaogaina o papa fou i luga o soʻo se
fa'asologa o fausaga tipi.
