Ke kumu kūʻai ʻo API tricone drill bits IADC216 4 5/8 iniha (118mm)
Hōʻike huahana
Hoʻohana nui ʻia ʻo 4 5/8 "TCI tricone bit i ka ʻeli ʻana i ka wai, ka ʻimi ʻana, ka lua hoʻokele HDD, ka hoʻokumu ʻana i ke kumu, aia kahi hoʻolālā jet hole, no laila hiki ke hana ʻia no ka hoʻohuli ʻana i ka wili.
Hoʻopaʻa ʻia ka bearing, ʻoi aku ka lōʻihi o ke ola hana ma mua o nā ʻāpana roller bearing open.
ʻO kēia ʻano o nā niho kila tricone bit he lua waena i kūpono no ka hoʻoheheʻe RC (Reverse Circulation drilling).
Hiki i ka IADC216 tricone bit ke wili i nā hana ʻoi aku ka paʻakikī ma mua o IADC126, ke koho ʻana i ka IADC kūpono e like me ka paʻakikī o nā pōhaku ʻo ia ka hana mua o ka wili kiʻekiʻe.ʻO Far Eastern Drilling kahi hale hana API i hōʻoia ʻia o ka tricone roller bit.
