Whakaahuatanga Hua

He mata keri kohatu API tricone hokohoko nui kei roto i te taonga i runga i te utu iti rawa me te kounga pai rawa atu mō te poka hohonu.
Whakaahuatanga Moka:
IADC: 127 - Mata pere hiri niho maitai me te tiaki ine mō ngā hanganga ngohengohe me te kaha pēhi iti me te kaha keri teitei.
Kaha Whakapūmau:
0 - 35 MPA
0 - 5,000 PSI
Whakaahuatanga Whenua:
Ko ngā toka tino ngohengohe, kāore i te paparanga, kāore i te pai te kiato pērā i te uku me te kirikiri kirikiri kāore i te pai te kiato, te kōhatu kirikiri mārō, te tote, te gypsum, me ngā waro mārō.
Ka taea e mātou te tuku atu i ngā mata wiri niho mira me ngā mata wiri tricone TCI o ngā rahi rerekē (mai i te 3” ki te 26”) me te nuinga o ngā waehere IADC.

Mā tēnei tikanga pai ake ka kaha ake te niho, ka ātete hoki ki te pānga i te mira, nā te mea ka tiakina te hanganga matūriki whakarewa i te wā e hangai ana, ā, ka kaha ake ngā niho. Ngā taipitopito o te Mīti Niho Rino.
Mā te tukanga maimoatanga wera o te Far Eastern Drilling ka whakakāhoretia te mata o te peera kia pakari ai te hanganga. Mā tēnei ka roa te mahi a te peera, ka pono hoki.
Ka aroturukitia tonutia, ka whakahoutia hoki te tukanga whakamārō niho nui kia pai ai te kounga o te putunga whakamārō niho.
He pai ngā wiri niho rino mō ngā hanganga tino ngohengohe me te iti o te kaha pēhi me te kaha ki te keri pērā i te uku, te paru, te tioka, me ētahi atu. He pai hoki mō ngā paparanga waenga me te kaha pēhi teitei, pērā i te kirikiri ngohengohe, te anhydrite, te kōhatu kōhatu waenga ngohengohe, te onepū waenga ngohengohe. Paparanga waenga me te paparanga mārō.

Te hanganga	Ko ngā hanganga ngohengohe he iti te kaha pēhi, he nui te kaha ki te keri, pērā i te paru, te gypsum, te tote, te pākeho ngohengohe, me ētahi atu.

Ko te tikanga o ngā niho matotoru o ngā kōne o ngā mata tricone he iti ake ngā niho, he mārō ake hoki te kaha o te keri i ngā toka. Nā te poto ake me te iti o ngā niho, ka taea e te mata tricone te keri i ngā toka ngohengohe, mārō rānei, ā, he teitei ake te ROP i ngā mata tricone TCI. Ka whakarei ake te mata o ngā kōne e te mata-mārō tungsten carbide.
Tena koa whakapā mai ki a mātou mō ētahi atu kōrero, kei te haere a Far Eastern ki ngā whakaaturanga i ngā whenua maha o te ao, ko te tumanako ka kōrero kanohi ki te kanohi ki a koe a mua tata nei.
