Nā ʻāpana ʻaila niho kila API no ka mīkini ʻeli wili i loko o ka waihona

Hale hana o nā ʻāpana wili tricone lua ʻaila i loko o ka waihona me ke kumu kūʻai hoʻemi
IADC: 115 he ʻāpana wili paʻa kila i hoʻopaʻa ʻia me ka niho kila me ka pale gauge no nā ʻano palupalu me ka ikaika compressive haʻahaʻa.
Eia nā kikoʻī o ka ikaika hoʻopaʻa o nā bit IADC115:
0-35 MPA/ 0-5,000 PSI
Wehewehe ʻĀina:
He kūpono ka ʻāpana tricone IADC115 no nā pōhaku palupalu, ʻaʻole i hoʻopaʻa pono ʻia a me nā ʻano ʻole stratifield e like me nā pōhaku limestone marl, nā paʻakai, gypsum, a me nā lanahu paʻakikī, nā lepo lepo a me nā one i hoʻopaʻa pono ʻole ʻia.
Loaʻa i nā ʻāpana tricone ke ʻano o ka Tungsten Carbide Insert (TCI) a me ka Mill Tooth (Steel Tooth) e like me nā mea ʻoki.
He maʻalahi lākou a hiki ke ʻoki i nā ʻano hoʻonohonoho he nui. Hoʻohana ʻia ka wili niho tricone drill bit no nā hoʻonohonoho palupalu. Hoʻohana ʻia nā TCI rotary tricone bits no nā hoʻonohonoho waena a paʻakikī. ʻO nā hoʻonohonoho pōhaku palupalu e komo pū ana me nā one i hoʻopaʻa ʻole ʻia, nā lepo lepo, nā pōhaku limestone palupalu, nā redbeds a me ka shale. ʻO nā hoʻonohonoho paʻakikī waena e komo pū ana me nā dolomites, nā pōhaku limestone, a me ka shale paʻakikī, ʻoiai ʻo nā hoʻonohonoho paʻakikī e komo pū ana me ka shale paʻakikī, ʻoiai ʻo nā hoʻonohonoho paʻakikī e komo pū ana me ka shale paʻakikī, nā pōhaku lepo, nā pōhaku limestone cherty a me nā hoʻonohonoho paʻakikī a me nā abrasive.
