Ko te waehere IADC he whakarāpopototanga mō "International Association of Drilling Contractors".
Ko te Waehere IADC mō ngā Mata Tricone e tautuhi ana i te hoahoa o tōna peera me ētahi atu āhuatanga hoahoa (HIKU, WAEWAE, WĀHANGA, TARAPATA).
Mā ngā waehere IADC ka māmā ake te whakaahua a ngā kai keri i te momo kohatu e rapuhia ana e rātou ki te kaiwhakarato.
E whai ana a Far Eastern i te pūnaha whakarōpūtanga o ngā moka IADC, e whakarōpūtia ai te moka e ngā mati tuatahi e toru e ai ki te hanganga i hangaia ai hei keri me te hoahoa whāriki/hiri i whakamahia.
He whakamārama mō te waehere IADC mō te mati tuatahi:
Ko te 1, 2, me te 3 e tohu ana i ngā Mīti Niho Rino, ko te 1 mō ngā hanganga ngohengohe, ko te 2 mō ngā hanganga waenga, ā, ko te 3 mō ngā hanganga mārō.
Ko te 4, 5, 6, 7 me te 8 e tohu ana i ngā Mīhini Whakauru Tungsten Carbide mō ngā momo pakeke rerekē, ko te 4 te mea ngawari rawa, ko te 8 te mea tino mārō.
He whakamārama mō te waehere IADC mō te mati Tuarua:
Ko te 1, 2, 3 me te 4 he wāhanga anō o te hanganga, ko te 1 te mea ngohengohe, ko te 4 te mea mārō.
He whakamārama mō te waehere IADC mō te mati tuatoru:
1 me te 3: te moka roera peera tuwhera paerewa (peera roera kore-hiri)
2: Paerewa tuwhera mō te keri hau anake
4 me te 5: te moka whēra hiri roera
6 me te 7: te moka whīra hiri
Tuhipoka:
*Te rerekētanga i waenga i te 1 me te 3:
3 me te whakauru carbide i te rekereke o te koeko, ko 1 kāore
*Te rerekētanga i waenga i te 4 me te 5:
5 me te whakauru kāpira ki te rekereke o te koeko, ko 4 kāore.
*Te rerekētanga i waenga i te 6 me te 7:
7 me te whakaurunga kāpira ki te rekereke o te koeko, ko 6 kāore.
He whakamārama mō te waehere IADC mō te mati tuawhā:
Ko ngā waehere reta e whai ake nei e whakamahia ana i te tūranga mati tuawhā hei tohu i ngā āhuatanga tāpiri:
A. Te tono hau

Ngā Momo Peera:
E whā (4) ngā momo hoahoa peera e whakamahia ana i roto i ngā mata keri trcione:
1) Paerewa Tuwhera Roera Momo:
I runga i ēnei poro ka huri noa ngā koeko. He rarangi pōro kei mua o tēnei momo poro, he rarangi roera kei muri.
2）: Pūwero Porowhita Tuwhera Paerewa mō te Keri Hau
He rite ngā kōne ki te #1, engari he werohanga hau tika ki ngā kōne hei whakamatao i ngā peera. Ka rere te hau ki roto i te kōne mā roto i ngā ara whakawhiti i roto i te pine. (Kāore mō ngā tono paru)
3）Ngā Momo Rōra Peera Hiri
He hiri O-Mīhini tō ēnei wahi me te puna hinu hei whakamatao i te peera.
He ārai ngā hiri i te paru me ngā haea hei whakaputa i ngā whāriki.
4) Ngā Momo Rōra Pupuri Pukapuka
He hinu/hinu anake te mea e whakamataohia ana e ēnei wahi, ā, he whāriki ihu, he hiri O-ring, he mea whakarite kia tino pai te mahi.
He whāriki hiri rapa me he whāriki hiri whakarewa ngā mōwhiti Tricone o te Rawhiti.
