Pi'i ta'avale vili IADC637 9 7/8” (250.8mm)
Fa'amatalaga o oloa
Fa'atau oloa siisii API TCI tricone vili bits ma tau fa'aitiitiga i le fa'asoa mai Saina falegaosimea mo faiga faigata.
Fa'amatalaga Bit:
IADC: 637 - TCI tusi talaaga fa'amaufa'ailoga fa'amau fa'amau fa'atasi ma fua fa'atatau mo fa'avae malo fa'asolo ma maualuga le malosi fa'amalosi.
Malosi fa'amalosi:
100 - 150 MPA
14,500 - 23,000 PSI
Fa'amatalaga o le eleele:
Ma'a'a ma'a'a ma'a'a lelei e pei o: limestone silica malo, streaks quarzite, pyrite ores, hematite ores, manetite ores, chromium ores, phosphorite ores ma maamora.
Far Eastern Drilling e mafai ona ofoina atu TCI bits i le tele o lapopoa (mai le 3 3/8" i le 26") ma le tele o tulafono a le IADC.
9 7/8 "o le 250mm le lautele, o le filo fesoʻotaʻiga o le 6 5/8 reg pine e tusa ai ma faʻamatalaga API.
IADC537 o lona uiga o le tricone roller bit e talafeagai mo le viliina o maʻa maʻaʻa pei o quarzite streaks, granite, ma isi. O le faʻamaufaʻailoga e faʻamaufaʻailogaina e faʻateleina ai le ola galue.
Tungsten carbide inserts (TCI) o se mea faʻapipiʻi faigata tele i le viliina o maa malo, o le mulivae o cones ma le lima-tua ua faʻapipiʻiina atoa i nifo Tungsten Carbide.
O se lapo'a masani i fanua eli, e vili ai le pu.I le viliina o le mining, o le numera muamua mo le IADC code e masani lava 6,7,8, ma le numera lona tolu e masani lava 2 ma 5.
E tusa ai ma fa'amatalaga a le IADC mo le tricone bit,"2" o lona uiga o le pa'u ta'avale matala matala, ma le "5" o lona uiga o le fa'amaufa'ailoga fa'amau fa'atasi ma le puipuiga fua.
I nisi o atunuu, 9 7/8"(250.8mm) e masani ona faʻaaogaina e vili vai lelei ma geothermal vaʻaia. O loʻo faʻasalalau rig e ala i le palapala palapala, nai lo le faʻapipiʻiina o le ea.
O le mea lea, mo faʻaoga eseese, e tatau ona tatou filifilia le saʻo tricone roller bits.
