ʻO ka mea hana API no ka ʻeli ʻana i nā ʻāpana pōhaku kumu kūʻai IADC412 ma ke kumukūʻai

HANA OKI:
ʻO Chisel ma ke ana, ogive ma nā lālani i loko.
Hoʻolālā ʻia no nā hana palupalu loa, e like me ka shale, ka limestone palupalu, ke one, ka conglomerate, ka dolomite palupalu a me ka ʻaila lanahu.
Noi: 4000-7000Psi
PALEKOLO LOLE:
Metala paʻa ma luna o ka lug;
E hoʻohana i ka carbide kūpaʻa ma ka lehelehe huelo a me ka lug.
NĀ HUA NUI:
IADC Code:412
Ke ʻoki ʻana:
Nā lālani o loko a me ka ihu: Conical
Nā Lālani Gage: Chisel
Palekana ʻo Gage Bevel: Pōʻai
He mea nui e koho i nā ʻāpana wili pōhaku kūpono ma mua o ka hoʻomaka ʻana i ka hana.
He palupalu paha ka paʻakikī o nā pōhaku, waena a paʻakikī a paʻakikī paha, ʻokoʻa iki paha ka paʻakikī o kekahi ʻano pōhaku, no ka laʻana, ʻo ka limestone, ʻo ka shale he pōhaku palupalu, ka limestone waena a me ka limestone paʻa, ke one waena a me ka pōhaku paʻa, etc. .
Ma ka hana wili,Hikina loaLoaʻa iā 15 mau makahiki a ʻoi aku ma mua o 30 mau ʻāina i nā lawelawe lawelawe e hoʻolako i nā drill bits a me nā soulutions drilling holomua no nā noi like ʻole.ʻO ka noi meeli lanahu, eli keleawe, hao hao, kala gulaa pēlā aku. Hiki ke hoʻopilikino ʻia nā ʻāpana drill like ʻole e like me ke kūkulu ʻana i nā pōhaku like ʻole no ka mea, loaʻa iā mākou kā mākou ihoAPI & ISOhale hana i hooiaioia o ka drill bits.Hiki iā mākou ke hāʻawi i kā mākou ʻenekinia hoʻonā inā hiki iā ʻoe ke hoʻolako i nā kūlana kikoʻī, e like meʻo ka paʻakikī o nā pōhaku, nā ʻano rig drilling, rotary speed, ke kaumaha ma ka bit a me ka torque.
