Whakaahuatanga Hua

Ngā mata keri toka hinu API tricone rarawe kei roto i te taonga me te utu whakaheke mai i te wheketere Haina
Ka taea e Far Eastern Drilling te tuku i ngā mata tricone TCI me ngā mata tricone niho maitai i roto i ngā rahi rerekē (mai i te 3" ki te 26") mete nuinga o ngā waehere IADC.
IADC: 237 he mata pere hiri niho rino me te tiaki ine mō ngā hanganga pakeke reo-waenga me te kaha pēhi teitei. Ko te kaha pēhi he 20-40MPA me te 3000-6000PSI/20 - 40 MPA/3,000 - 6,000 PSI.
Ka whakamahia ngā mata toru-okene IADC237 mō ngā kohatu onepū he rārangi kiripaka, he kōhatu papa mārō, he tiēre rānei, he dolomite tioata, he konganuku hematite, me ngā kirikiri mārō.

Ko te kimi i ngā mata keri toka e tika ana te taahiraa tuatahi i mua i te mahi keri.
Ka tohaina e mātou ētahi kōrero taipitopito mō te whiriwhiri i ngā mata tricone tika.
A. E rua ngā momo mata toru-pūwero e hangai ana ki te momo niho.
1) Ngā moka tricone niho maitai (IADC1**,IADC2**,IADC3**)
2) Ngā moka tricone TCI (IADC4**,IADC5**,IADC6**,IADC7**,IADC8**)
E whā ngā momo mata tricone e hāngai ana ki te momo peera.
1) Te whārite o te puka (IADC**6,IADC**7)
2) Whero roera (IADC**4,IADC**5)
3) Te whāriki tuwhera (IADC**1)
4) Te whāriki hau (IADC**2,IADC**3)
Ētahi kōrero:
1) He pai ake te whiriwhiri i te mata tricone maitai mō ngā hanganga ngohengohe, pērā i te paru.
2) He pai ake te whiriwhiri i te kōhatu tricone TCI, hei tauira, te kōhatu pākeho.
3) Ko te peera roera, te peera hautaka e whakamahia ana i roto i ngā kaupapa keri puna wai.
4) Ko ngā peera tuwhera, te peera hau, me te peera roera e whakamahia ana i roto i ngā kaupapa keri maina.
5) Kōwhiria te mata tricone kia rite ki te kaha pēhi
