12,000 - 14,500 PSI
Whakaahuatanga Whenua:
Ngā toka mārō waenga, me ngā toka whakakoi pērā i te onepū me ngā rārangi o te kuata, te kōhatu mārō, te tiēre rānei, ngā konganuku hematite, ngā toka whakakoi mārō, kua pai te whakapiripiri pērā i: ngā onepū me te here kuata, ngā dolomite, ngā kirikiri kuata, te magma me ngā toka matotoru kua memeha.
Ka taea e Far Eastern Drilling te tuku i ngā mata wiri tricone o ngā rahi rerekē (mai i te 3 7/8” ki te 26”) me te nuinga o ngā waehere IADC.
He rahi noa te 9 7/8 inihi (250mm) mō te keri poka hohonu pērā i te keri puna hinu me te hau, ā, he rahi noa anō hoki mō te keri poka pairati whakapae.
Kei te rauemi tapahi, kei te wātea ngā mata wiri rapa silicone i roto i ngā momo TCI (whakaurunga carbide) me ngā momo niho maitai. Ko te iADC517 he mata wiri rapa silicone momo TCI.
Hanganga whāriki.
He peera porowhita tino tika me ngā mata pana e rua, he koeko maukati pōro, he mata mārō o te peera pane, he peera koeko kua whakakikoruatia ki te koranu whakaiti waku, kātahi ka whakakikoruatia ki te hiriwa, e whakapai ake ana i te ātete kakahu me te ātete whakapataritari o te peera, ā, he pai mō te tere tiketike.
Te hiri me te whakahinuhinu.
Ko te kete hiri whakarewa matatau he mea tito mai i ngā hiri whakarewa e rua me ngā whakakaha pīngore e rua. Mā ngā whakakaha pēhi ka pai te hononga i waenga i ngā mata hiri e rua o ngā mowhiti whakarewa mā te kaha pīngore kia tutuki ai te hiri o ngā peera. I te wā e keri ana, he āhua hihiri ngā hiri whakarewa, ko ngā whakakaha he pūmau, ka whakapai ake i te pono me te pakari o te hiri peera, ā, mā te pūnaha whakamāmā pēhanga me te hinu matatau ka tino whakapai ake i te pono o te whakahinuhinu.
