Ifekthri ye-API ye-geothermal well tricone drilling bits esitokweni
Incazelo Yomkhiqizo
I-Wholesale API uwoyela i-tricone rock drill bits esitokweni ngentengo ehlisiwe evela embonini yase-China
I-Far Eastern Drilling inganikeza izingcezu ze-TCI trione namazinyo ensimbi ama-tricone bits ngobukhulu obuhlukahlukene.kusuka ku-3 "kuya ku-26") kanyeIningi lamakhodi e-IADC.
I-IADC: I-237 ijenali yezinyo lensimbi evalwe ibhithi elinesikali esinokuvikelwa kwegeji yokwakheka okuqinile okuphakathi nendawo okunamandla acindezelayo aphezulu.Amandla okucindezela ngu-20-40MPA kanye no-3000-6000PSI/20 - 40 MPA/3,000 - 6,000 PSI.
I-IADC237 triocne bits izosetshenziselwa amatshe esihlabathi anemigqa ye-quartz, i-limestone eqinile noma i-chert, i-crystalline dolomite, i-hematite ores, namashali aqinile.

Ukuthola izingcezu zokumba amatshe kuyisinyathelo sokuqala sephrojekthi yokumba.
Sizokwabelana ngemininingwane mayelana nendlela yokukhetha izingcezu ze-tricone ezifanele?
A.Kunezinhlobo ezi-2 zezingcezu ze-triocne ezisuselwe ohlotsheni lwamazinyo.
1) Amabhithi ensimbi ye-ttooth trione (IADC1**,IADC2**,IADC3**)
2) I-TCI trione bits (IADC4**,IADC5**,IADC6**,IADC7**,IADC8**)
B.Kunezinhlobo ezi-4 zamabhithi e-tricone asekelwe ohlotsheni lwe-bearing.
1) Ijenali ephethe (IADC**6,IADC**7)
2) I-roller bear (IADC**4,IADC**5)
3) I-Open bear (IADC**1)
4) I-Air bear (IADC**2,IADC**3)
C Eminye imininingwane:
1) Ukwakheka okuthambile kungcono ukhethe ibhithi lensimbi ye-tricone, isb udaka.
2) Ukwakheka okuqinile kungcono ukhethe i-TCI trione bit, isb.
3) I-roller bear, ijenali isetshenziswa kakhulu ezinhlelweni zokumba imithombo yamanzi.
I-4) Ama-bearings avulekile, i-air bear, i-roller bear isetshenziswa kakhulu emisebenzini yezimayini.
5) Khetha i-tricone kancane njengamandla acindezelayo
I-PSI | Ikhodi ye-IADC | Ukwakheka |
0 ~ 4000 | IADC1** | ubumba namatshe esihlabathi, usawoti |
4000~8000 | IADC2** | i-marl limestones, i-gypsum, namalahle aqinile. |
8000 ~ 15000 | IADC3** | amatshe esihlabathi ane-quartz binder, amatshe esihlabathi aqinile, ama-quartz shales aqinile, i-magma, namadwala e-metamorphic. |
15000 ~ 25000 | IADC4** | ama-shales, ama-dolomite, amatshe esihlabathi, ubumba, usawoti, nama-limestones. |
25000~40000 | IADC5**, IADC6** | amatshe esihlabathi ane-quartz binder, ama-dolomite, ama-quartzite shales, i-magma kanye namadwala angama-coarse-grained metamorphic |
Ngaphezu kuka-40000 | IADC7**, IADC8** | i-limestones eqinile ye-silica, imigqa ye-quartzite, i-pyrite ores, i-hematite ores, i-magnetite ores, i-chromium ores, i-phosphorite ores, nama-granite |
