ʻenehana wili ʻana | Pehea e koho ai i kahi Drill Bit no nā ʻano palupalu, nā ʻano abrasive, a me nā ʻano hoʻololi maʻalahi?

ʻO ka mea nui, i ka lawe ʻana i ka aila a i ʻole ka wai, pono e noʻonoʻo ʻia nā ʻano mea like ʻole, e like me ka lithology, kahi ʻāpana luawai, a me ke ʻano o ka wellbore. Ma ka hooponopono anaAPI maʻamau tricone bitsme nā kūlana kūikawā a me nā kūlana wili, hiki iā ʻoe ke hoʻomaikaʻi i ka maikaʻi o ka wili a hōʻemi i ka ʻaʻahu a me ka waimaka ma katungsten carbide i nā ʻāpana hoʻokomo.

No laila, pehea mākou e koho ai i ka ponohookomo niho tricone bitsa i ʻolewili niho tricone bitse hoʻonui i ka hana wili a me ka uku-pono?

1. He aha nā ʻano o Drill Bits Aia ma muli o ka hana?

Hiki ke hoʻokaʻawale ʻia nā ʻāpana Drill i nā ʻano like ʻole e pili ana i ka hana, me:

• ʻO nā bit drill anawaena pihano ka wili ʻana holoʻokoʻa (e laʻa,ʻekolu cones drill bit).
• Nā ʻāpana drill Annular(core barrel drill bit), e like mehookomo i na wili niho, i hoʻohana ʻia no nā pono kiʻi koʻikoʻi.

No nā hana palupalu,kauo bitsa i ʻolewili niho bitsʻoi aku ka maikaʻi o ke koho ʻana, ʻoiai no nā hana ʻoi aku ka paʻakikī a me ka abrasive,tungsten carbide tricone drill bitshe kūpono.

2. He aha nā ʻano o nā Tricone Bits?

Nā ʻāpana Tricone, e like mecpahu oka me nā cones huilaaTCI drill bits, ʻike ʻia no ko lākou wahi liʻiliʻi liʻiliʻi ma waena o nā niho a me ka hoʻokumu ʻana, e alakaʻi ana i ke kaomi bit kiʻekiʻe, hoʻemi ʻia ka torque hana, a me ka lōʻihi o ka lau. ʻO kēia mau hiʻohiʻona e kūpono iā lākou no nā hoʻokumu paʻakikī, mewai puna wai tricone bitsanā ʻāpana luawai ʻaila.

3. ʻEhia mau ʻano o nā ʻāpana Tricone i laila?

• Ma ka helu o na cones: Aiahoʻokahi-cone,lua-cone, atri-cone bits.TCI tricone bitsawili niho tricone bitsmea maʻamau no nā noi like ʻole, memining tricone bitsanā pahu pahu hau.
• Ma ka hale: Aiaʻano kinoaʻano kino ʻoletricone bits, ua hoʻolālā ʻia kēlā me kēia no nā kumu like ʻole.
• Ma ke ʻano niho:Nā ʻāpana niho wilihoʻohana pinepine ʻia i nā ʻano palupalu, ʻoiaihookomo i na wili nihomenā mea hoʻokomo tungsten carbideʻoi aku ka maikaʻi no nā hana paʻakikī.

4. He aha nā ʻāpana o ka Bit-cone Bit? He aha kā lākou mau hana?

Awili wili tungsten carbideaia kekahi mau mea koʻikoʻi:

• Kino bit a me nā lima: Hoʻohui i ka mea hana wili, hāʻawi i ke kākoʻo no ka bit.
• Cones: Loaʻa i ka cone hoʻokahi, ʻelua-cone, a i ʻole tri-coneTCI drill bitsʻoi aku ka maikaʻi ma nā hana abrasive.
• Nā Bearings: E hōʻoia i ka holo mālie o nā cones a lawe i nā ukana axial a me radial.ʻO nā ʻāpana huilahoʻohana maʻamau i nā bearings kiʻekiʻe e hoʻonui i ka lōʻihi.
• Nā awa wai: Pono no ka holo ʻana o ka wai.Hoʻokuʻu i nā ʻāpana(loaʻa mawai puna wai tricone bits) hoʻohana i nā nozzles e kuhikuhi pono i ka wai wili e hoʻomaʻemaʻe i nā ʻokiʻoki.
