ʻO API ka mea hana i nā ʻāpana wili wai me nā mea hoʻokomo ʻo Chisel

ʻO ke kumu kūʻai hoʻokūkū a me ka hana maikaʻi loa, ʻo ka 7 1/2 "IADC537G kahi kumu kuʻuna a maʻamau i ka hoʻoheheʻe wai wai, 4" a i ʻole 4 1/2" mau paipu e hoʻokomo mau ʻia ma hope o ka wili ʻana o ka lua 190mm.
Ua hoʻopaʻa ʻia kēia tungsten carbide hoʻokomo i ka wai drill bits i ka bearing a me ka pale tungsten carbide gauge, hiki iā ia ke hana me ke kaʻa i kau ʻia i ka drill rig a i ʻole hydraulic drill rig.
Me ka manawa hoʻopuka wikiwiki a me ka lawelawe ʻana ma hope o ke kūʻai aku, ua lawelawe ʻo Kina Far Eastern no mroe ma mua o 35 mau ʻāina i ka makahiki 10 i hala I ka papahana wili, Loaʻa iā mākou ka ʻike e hoʻolako i nā drill bits a me nā soulutions drilling holomua no nā noi like ʻole. ʻO ka noi mewai luawai wili aila kahua, kinoea maoli, ke kālaihonua 'imi, driectional boring, Hiki ke hoʻopilikino ʻia nā ʻāpana drill like ʻole e like me ka hoʻokumu ʻana i nā pōhaku like ʻole no ka mea iā mākou ponoʻīAPI & ISOhale hana i hooiaioia o tricone drill bits. Hiki iā mākou ke hāʻawi i kā mākou ʻenekini 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. He mea kōkua nō hoʻi iā mākou e ʻimi i nā bit drill siutable ma hope o kou haʻi ʻana iā mākouwili lua kuʻekuʻe a i ʻole ka wili ʻana i ka ʻaila , ʻaila luawai.
