ʻO ka ʻeli ʻana o ka triocne API IADC125 17 1/2 ʻīniha (444.5mm)

Hoʻohana ʻia ka ʻāpana tricone niho wili no ka ʻeli ʻana i nā ʻano palupalu, ʻoi aku ka maikaʻi o ka ROP (Rate of Penetration) ma mua o ka ʻāpana tricone TCI, ʻoi aku ka wikiwiki o ka ʻeli ʻana ma mua o ka ʻāpana tricone Tungsten Carbide Insert i ka ʻeli ʻana i ka pōhaku lepo a i ʻole nā ​​​​pōhaku pipili ʻē aʻe.
He kūpono ka TCI tricone bit no ka ʻeli ʻana i nā pōhaku paʻakikī, akā hana mau ʻia ka bit-balling i ka ʻeli ʻana i nā ʻano palupalu a pipili e pale ai i ka iho ʻana o ka wili bit.
He lōʻihi nā niho o nā ʻāpana tricone niho kila ma mua o nā ʻāpana TCI tricone i hiki iā ia ke ʻeli i nā ʻano palupalu ma ka ROP kiʻekiʻe.
I nā papahana ʻeli ʻaila, hiki i ka ROP ke hōʻea i 30 mika i kēlā me kēia hola i ka ʻeli ʻana i ka ʻāpana pāpaʻu.
Ke koho ʻoe i kahi ʻūlili wili FAR EASTERN, loaʻa iā ʻoe ka ʻūlili kūpono no ka hoʻohana kūpono, no laila hiki iā ʻoe ke noho i loko o ka lua no ka manawa lōʻihi me nā huakaʻi liʻiliʻi, ma ke kumukūʻai haʻahaʻa no kēlā me kēia kapuaʻi. No ka mea, ua hana pono mākou i kēia ʻenehana no nā makahiki he 15 a ʻoi, ua hilinaʻi mākou i ko mākou hoʻoilina a ʻaʻohe mea hana ʻūlili ʻē aʻe e hiki ke hoʻokūkū me ko mākou ʻike.
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 ʻōwili kahua no nā noi like ʻole.
Ma ke ʻano he hale hana wili ʻoki alakaʻi ma Kina, ʻo ka hoʻonui ʻana i ke ola hana o ka wili ʻoki kā mākou pahuhopu. Hoʻāʻo mau mākou e hoʻomaikaʻi i nā ʻāpana me nā helu komo kiʻekiʻe. ʻO kā mākou pahuhopu ke kūʻai aku i ke kūlana kiʻekiʻe me ke kumu kūʻai haʻahaʻa loa. E kōkua ka maikaʻi a me ka ʻenehana wili hikina mamao iā ʻoe e hoʻokō i nā mea hou aku!
