Fa'alilo vili loloto IADC127 12 1/4” (311mm)
Fa'amatalaga o oloa
Fa'atau oloa siisii API tricone rock bit i totonu o fa'asoa e fa'atatau i le fa'atauga pito i lalo ma le lelei lelei mo le loloto lelei.
Fa'amatalaga Bit:
IADC: 127 - u'amea nifo u'amea fa'amau fa'amau fa'amau fa'atasi ma fua fa'atatau mo fa'amalulu fa'avae e maualalo le malosi fa'amalosi ma maualuga vili.
Malosi fa'amalosi:
0 - 35 MPA
0 - 5,000 PSI
Fa'amatalaga o le eleele:
O ma'a vaivai tele, e le'i fa'asalaina, e le lelei ona fa'apipi'i e pei ole omea e le lelei ona fa'apipi'iina ma ma'a oneone, marl limestones, masima, gypsum, ma malala malala.
E mafai ona matou ofoina vili vili ma TCI tricone drill bits i ituaiga eseese (mai le 3 "i le 26") ma le tele o IADC Codes.
O lenei metotia sili e maua ai se nifo malosi, sili atu le a'afiaga nai lo le viliina ona o le fausaga o u'amea i le taimi o le faʻamalosi e puipuia, e mafua ai le malosi o nifo. Fa'amatalaga o le Uila nifo u'amea.
Far Eastern Drilling faagasologa togafitiga vevela filifili carburizes luga ofuina ofuina ina ia mautinoa le faigata o le fausaga. O lenei mea e maua ai le faʻatinoina o le faʻatauga umi ma faʻatuatuaina.
E fa'aauau pea ona mata'ituina ma fa'afouina le fa'agasologa o nifo mata'utia e fa'amautinoa ai le maualuga o le lelei o tupe teu fa'asaga.
u'amea nifo u'amea e talafeagai mo fa'avae vaivai tele ma le malosi compressive maualalo ma drillability maualuga e pei o le omea, ma'a palapala, penisina, ma isi. E talafeagai foi mo strata feololo ma le malosi compressive maualuga, e pei o shale vaivai, anhydrite, ma'a vaivai vaivai, medium. maa oneone vaivai. La'au feololo ma se fa'alava malo.

O nifo mafiafia i koni o tricone bits o lona uiga o nifo laiti ma maa malosi e mafai ona viliina, pupuu ma laiti nifo e vili ai nifo tricone drill bit e mafai foi ona viliina maa vaivai pe feololo ma le ROP e maualuga atu nai lo TCI tricone bits. O luga o cones e faʻaleleia e le tungsten carbide e faʻafefe.
Fa'amolemole fa'afeso'ota'i mai matou ina ia maua nisi fa'amatalaga, Far Eastern e auai i fa'aaliga i le tele o atunu'u i le lalolagi atoa, fa'amoemoe e talanoa fa'afesaga'i ma oe i se taimi lata mai.
