Hana ʻia ka luawai kahua aila API kūʻai nui ʻo TCI tricone bit no ka hoʻokumu paʻakikī

He mea nui ke koho ʻana i ka tricone kūpono i ka wā o ka papahana ʻeli. ʻO IADC537 ka TCI journal sealed bearing bit me ka pale gauge no nā ʻano palupalu a waena me ka ikaika compressive haʻahaʻa.
ʻAʻole paha like ka paʻakikī o nā pōhaku, e like me ka palupalu, waena a me ka paʻakikī a i ʻole ka paʻakikī loa. ʻAʻole paha like ka paʻakikī o kekahi ʻano pōhaku, no ka laʻana, ka pōhaku lepo, ka pōhaku one, he pōhaku lepo palupalu ka shale, ka pōhaku lepo waena a me ka pōhaku lepo paʻakikī, ka pōhaku one waena a me ka pōhaku one paʻakikī, a pēlā aku.
He 15 mau makahiki a ʻoi aku ma mua o 30 mau ʻāina ka ʻike lawelawe o Far Eastern e hoʻolako i nā ʻāpana wili a me nā ʻuhane wili holomua no nā noi like ʻole. ʻO ka noi e pili ana i ke kahua aila, ke kinoea kūlohelohe, ka ʻimi honua, ka hoʻowali driectional, ka wili ʻana i ka lua wai, hiki ke hoʻopilikino ʻia nā ʻāpana wili like ʻole e like me nā ʻano pōhaku like ʻole no ka mea he hale hana ponoʻī kā mākou API a me ISO o nā ʻāpana wili tricone. Hiki iā mākou ke hāʻawi i ka hopena o kā mākou ʻenekinia ke hiki iā ʻoe ke hoʻolako i nā kūlana kikoʻī, e like me ka paʻakikī o nā pōhaku, nā ʻano o ka wili wili, ka wikiwiki wili, ke kaumaha ma ka ʻāpana a me ka torque.
Hiki iā Far Eastern Drilling ke hāʻawi i nā ʻāpana tricone i nā nui like ʻole (mai 3” a i 26”) a meka hapa nui o nā code IADC.
