Nā ʻāpana wili API TCI tricone kūʻai nui me ke kumu kūʻai hoʻēmi ʻia ma ka waihona mai ka mea hoʻolako Kina no ka wili luawai
Wehewehe ʻana o ka Bit:
IADC: 637 - ʻO ka ʻāpana bearing i hoʻopaʻa ʻia me ka puke pai TCI me ka pale gauge no nā ʻano paʻakikī waena me ka ikaika compressive kiʻekiʻe.
Ikaika Hoʻopaʻa:
100 - 150 MPA
14,500 - 23,000 PSI
Wehewehe ʻĀina:
Nā pōhaku paʻakikī a paʻa pono e like me: nā pōhaku limestone silica paʻakikī, nā kaha quarzite, nā ʻāpana pyrite, nā ʻāpana hematite, nā ʻāpana magnetite, nā ʻāpana chromium, nā ʻāpana phosphorite a me nā granite.
Hiki iā mākou ke hāʻawi i nā ʻāpana TCI i nā nui like ʻole (mai 3 3/8" a 26") a me ka hapa nui o nā code IADC.

Hoʻomaopopo nā hoʻonohonoho hydraulic like ʻole i ka hoʻomaʻemaʻe pono ʻana o ka bit a me ka lua i nā noi he nui. Hiki i nā nozzles ke hoʻomaʻemaʻe i ke kuʻekuʻe wāwae a me nā niho kuʻekuʻe wāwae e pili ana.
ʻOi aku ka liʻiliʻi o nā ʻāpana ma kēlā me kēia ʻāpana, ʻoi aku ka liʻiliʻi o nā huakaʻi mai loko mai o ka lua, a me nā lā liʻiliʻi e hoʻopau ai i kāu luawai e hōʻemi ana i kāu kumukūʻai no ka kapuaʻi.

Hoʻokumu ʻana	Hoʻokumu waena me ka ikaika compressive haʻahaʻa, e like me ka shale waena, shale palupalu, limestone palupalu waena, limestone palupalu waena, one pōhaku palupalu waena, hoʻokumu waena me nā interbeds paʻakikī a abrasive, a pēlā aku.

He loea ʻo Far Eastern i nā ʻāpana wili, e like me nā ʻāpana tricone, nā ʻāpana PDC, ka mea wehe puka HDD, nā mea ʻoki wili kumu no nā noi like ʻole. ʻO ka noi e pili ana i ke kahua ʻaila, ke kinoea kūlohelohe, ka ʻimi honua, ka hoʻopōʻino kuhikuhi, ka mining, ka ʻeli ʻana i ka lua wai, HDD, ke kūkulu ʻana a me ke kahua...
Ma ke ʻano he hale hana wili ʻoi loa ma Kina, ʻo ka hoʻonui ʻana i ke ola hana o ka wili ʻo kā mākou pahuhopu. Hoʻāʻo mau mākou e hoʻomaikaʻi i nā ʻāpana me nā helu komo kiʻekiʻe. ʻO kā mākou misionari ka hoʻohaʻahaʻa i ke kumukūʻai o ka wili ʻana-no-ka-mika. .ʻO kā mākou pahuhopu ke kūʻai aku i ke kūlana kiʻekiʻe me ke kumukūʻai haʻahaʻa loa.
