Whakaahuatanga Hua

Ko te pane hurihuri API rarawe mō te taputapu keri kei roto i te taonga i runga i te utu iti rawa me te kounga pai mai i te wheketere Haina
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.

E ai ki te rauemi tapahi, ka taea te wehewehe i ngā moka kōne e toru ki te moka TCI me te moka Niho Mira.
Ko te mata keri tricone niho mira IADC127 he mea hanga mō te hanganga ngohengohe rawa. He mea nui te whiriwhiri i ngā mata keri toka tika i mua i te tīmatanga o te kaupapa.
Ka taea e te pakeke o ngā toka te ngohengohe, te pakeke waenga, te pakeke tino pakeke rānei, ka rerekē pea te pakeke o tētahi momo toka, hei tauira, he toka kōhatu, he toka onepū, he toka kōhatu ngohengohe, he toka kōhatu waenga, he toka kōhatu pakeke hoki te kirikiri, he toka kōhatu waenga, he toka onepū pakeke hoki, me ētahi atu.
I roto i te kaupapa keri, he 15 tau a Far Eastern me te neke atu i te 30 whenua o te wheako ratonga ki te whakarato i ngā mata keri me ngā wairua keri matatau mō ngā tono maha. Kei roto i ngā tono ko te mara hinu, te hau māori, te tūhura whenua, te keri awa, te keri, te keri puna wai, te HDD, te hanga, me te turanga. Ka taea te whakarite i ngā momo mata keri kia rite ki ngā hanganga toka rerekē nā te mea kei a mātou ake wheketere tohu API me ISO mō ngā mata keri. Ka taea e mātou te whakarato i te otinga a tā mātou miihini ina taea e koe te whakarato i ngā āhuatanga motuhake, pēnei i te pakeke o ngā toka, ngā momo taputapu keri, te tere hurihuri, te taumaha o te mata me te taipana. Ka āwhina hoki mātou ki te kimi i ngā mata keri e tika ana i muri i tō whakamōhio mai ki a mātou mō te keri puna poutū, te keri whakapae rānei, te keri puna hinu, te keri Kore-Keri, te whakatō turanga rānei.

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 mata niho mira 8 1/2 inihi IADC127GT he rahi noa me ngā whakaurunga Edge-Row i roto i te keri puna wai, he pai te mahi me ngā taputapu keri iti te kaha, ā, e whakamahia whānuitia ana puta noa i te ao.
Ko te āhuatanga o te waehere IADC, ko te GT te tikanga he tiakitanga TCI kei te hiku o te hāte (ngā waewae), ko te T te tikanga he niho TCI kei te taha o te rarangi koeko.
Mā te reta T, ka taea e te mata tricone niho rino te keri i ngā toka ngohengohe me te kore e manukanuka ki te whakaiti. Ko te mata tricone niho rino e kiia ana ko te mata tricone niho mira ka taea te keri i te paru ngohengohe, tae atu ki te kōhatu kirikiri ngohengohe, he mata mārō ngā koeko ki te tungsten carbide, he porotaka te peera, ā, he pōro te raka, he peera hiri-O-ringi-HNBR kounga teitei, he pūnaha whakakī hinu te whakahinuhinu i te peera, he roa te ora mahi.
