Ke alakaʻi piha i ke koho ʻana a me ka hoʻohana ʻana i ka Tricone Drill Bit

I ka wiliwili ʻana, kadrill bithe mea paahana mua no ka wawahi ana i na pohaku. ʻO ka maikaʻi o ka bit a me kona kūlike me ke ʻano hoʻokumu, nā waiwai pōhaku, a me nā kūlana wili e pili pono i ka wikiwiki wili. ʻO ke koho ʻana i ke ʻano bit maikaʻi loa a me nā ʻāpana wili e pili ana i nā kūlana hoʻokumu ke kī i ka hoʻomaikaʻi ʻana i ka pono wili a me ka hoʻohaʻahaʻa ʻana i nā kumukūʻai. ʻO ka hoʻoheheʻe ʻana i ka pūnāwai hohonu e hālāwai me nā ʻano hana like ʻole a me nā ʻano pōhaku me nā waiwai like ʻole, e hana anadrill bitkoho i kahi hana paʻakikī.

1. Ke Kaʻina koho Bit Empirical

ʻIke ʻia hoʻi ʻo ka Field Drilling Data Method, he hana kūpono kēia a hoʻohana nui ʻia i waena o nā ʻenehana kahua. Ke hilinaʻi nei ia i ka nānā ʻana i ka ʻikepili mai nā pūnāwai kokoke i ka wahi like, e kālele ana i nā ʻano bit i loaʻa ka kiʻi kiʻi kiʻekiʻe i hoʻoheheʻe ʻia a me ka awelika o ke komo ʻana ma lalo o nā kūlana like ʻole a me ka hohonu. He maʻalahi kēia ʻano hana, kūpono a kūpono hoʻi no nā wahi me nā ʻano like.

2. ʻO ke ʻano koho bit ma muli o ka Reference

No ka lanakila ʻana i nā palena o nā ʻano empirical, ua hoʻokomo kēia ala i ka ʻikepili logging acoustic ma ke ʻano he hōʻailona hoʻokumu ʻole, e hoʻonui ana i ka pololei ʻepekema. ʻIke ʻia ʻo "Reference Method," pono ia i nā mea hoʻolako bit e hoʻohālikelike i nā ʻāpana hoʻonohonoho i loaʻa mai ka logging acoustic me nā mamana koho bit standardized, e hiki ai i nā ʻōlelo kuhikuhi bit pololei.

3. Kūlike like Koho Bitʻano hana

Ke hahai nei kēia ʻano hana i kahi ala i hoʻonohonoho ʻia:

• E kiʻi i ka ʻikepili drillability formation ma o ka hoʻāʻo ʻana a i ʻole nā ​​hana wānana.
• E hoʻohana i ka ʻikepili helu ma ka ʻikepili drillability pōhaku i hōʻiliʻili ʻia no ka hoʻoholo ʻana i ka hiki ke hoʻoheheʻe maʻamau (Kd) a me ka hewa maʻamau (S) no kēlā me kēia hana.
• Me ka palapala koho bit code IADC, e hoʻohālikelike i ke kiʻekiʻe o ka hana drill no ka ʻike ʻana i nā ʻano bit kūpono no kēlā me kēia kūkulu ʻāina.

4. Manaʻo ʻia nā ʻāpana wili no nā hana a pau

ʻO ka hana maikaʻi loa o adrill bithilinaʻi i ke koho ʻana i ke ʻano bit pono a me ka hoʻohana ʻana i nā ʻāpana wili kūpono.

5. Drillability Profile a me ke koho Bit no ka hoʻokumu ʻana o Puguang

Me ka hoʻohana ʻana i ka ʻikepili honua a me ka hoʻopaʻa inoa ʻana mai nā pūnāwai ma ka ʻāina ʻo Puguang, ua kālailai ʻia ka hana bit a hoʻokaʻawale ʻia e nā papa honua a me nā nui luawai ma o ka "Drill Bit Technical Efficiency Index" (JX=VL=average mechanical penetration rate × bit footage).

• Palapala Hoʻokumu a me Lithology: Nā kikoʻī i nā inoa papa, mānoanoa, a me nā ʻano pōhaku i ʻike ʻia ma ka ʻāina ʻo Puguang.
• ʻO ka Drillability Profile a me ke Koho Bit Manaʻo ʻia: Hoʻokaʻawale i nā hoʻokumu ʻana e nā code IADC e pili ana i nā pae mākaukau drill.
• Nā Manaʻo Koho Bit Empirical: Ma muli o ka ʻikepili hoʻohana ʻāpana ʻāpana, hāʻawi kēia i nā hoʻonohonoho bit i manaʻo ʻia no nā nui maʻamau.
• Manaʻo Manaʻo ʻEnekinia: E helu ana i ke kaumaha-ma-bit (WOB), RPM, ka helu mana hydraulic, a me ka paepae WOB ma muli o ka drill pōhaku.

6. Nā alakaʻi no ke koho ʻana a me ka hoʻohana ʻana i ka Bit Drill Bit

(a) Koho Ma muli o ka Lithology a me ka Drill hiki: Drill bit koho e noʻonoʻo mua i ka hoʻokumu ʻana i ka lithology a me ka hoʻokaʻawale ʻana i ka mākaukau drill, me nā hoʻololi e pili ana i nā kiʻi lithological i ʻike ʻia i ka wā wili.

(b) Nā Manaʻo Manaʻo Nui noPDC Bits: ʻO ka maʻamau,PDC bitskūpono ia no nā ʻano haʻahaʻa haʻahaʻa.

• No nā ʻano palupalu me ka plasticity kiʻekiʻe, e hoʻohana i nā ʻāpana me ke anawaena nuiPDCnā mea ʻoki a me ka ʻoki kiʻekiʻe e hoʻomaikaʻi i ka hana haʻihaʻi pōhaku.
• No ka hoʻokumu ʻana i ka paʻakikī me ka haʻahaʻa haʻahaʻa, e koho i nā ʻāpana me nā mea ʻoki ʻoki PDC liʻiliʻi a me ka haʻahaʻa haʻahaʻa e pale ai i ka haki ʻoki a hoʻolōʻihi i ke ola mea hana.

(c) Hoʻonui i nā ʻāpana hoʻoheheʻe ʻana ma muli o ke ʻano o ka Bit Structure and Formation Conditions: E hoʻonohonoho i nā ʻāpana—e like me WOB, RPM, a me ka mana hydraulic—ma muli o ke ʻano o ka bit a me nā kūlana hoʻokumu, a e hōʻoia e noho lākou i loko o nā pae i manaʻo ʻia.

(d). ʻO ke koho ʻana ma ka hohonu a me ke kūkulu ʻana:

• No ka hoʻokumu ʻana i ka hohonu, e hoʻohui i nā bits PDC me nā kaʻa downhole e hoʻohana i ka mana RPM kiʻekiʻe.
• No ka hoʻohana ʻana i ka ʻeleʻele nui, hoʻonui i ka WOB a hoʻemi i ka RPM e like me ke kūpono no ka hoʻonui ʻana i ka pono wili.
