ʻO Tricone Bit VS PDC Bit, ʻO wai ke koho maikaʻi loa no ʻoe?
ʻO Tricone Bit VS PDC Bit, ʻO wai ke koho maikaʻi loa no ʻoe?
ʻO ka drill bit he mea hana e wili ai i ka lua cylindrical (wellbore) e ʻike ai a unuhi i ka ʻaila maʻemaʻe a me ke kinoea maoli.
I ka ʻoihana ʻaila a me ka ʻea, he mea nui ka loaʻa ʻana o nā lako kūpono no kēlā me kēia o kāu mau papahana. Hiki i ka hoʻohana ʻana i nā mea hana hewa ke alakaʻi i nā pōʻino, no laila he mea nui e loaʻa ka ʻike kūpono ma mua o ka hoʻomaka ʻana. He mea maʻamau ka tricone bits a me ka PDC drill bits i ka ʻoihana ʻaila a me ke kinoea. ʻO Tricone Bit VS PDC Bit, ʻO wai ke koho maikaʻi loa no ʻoe?
ʻO Tricone Bit i ka ʻoihana ʻaila a me ke kinoea
Ua haku ʻia ka tricone bit e Hughes engineer a me Ralph Neuhaus a he mea hoʻololi ia o ka pahu drill ʻelua-cone mua a Baker Hughes. ʻO ka tricone bit he pahu drill me ke poʻo i māhele ʻia i ʻekolu ʻāpana nui. Aia i loko o ka tricone bit ʻekolu mau cones e hana ana i loko o kekahi me kona lālani o nā niho ʻoki. Hoʻohana ʻia nā ʻāpana huila-cone e wili i nā hana mai ka palupalu a i ka paʻakikī. Hoʻohana nā mea palupalu i nā ʻāpana niho kila a me ka carbide tungsten paʻakikī.
ʻO ka pōmaikaʻi nui loa i loaʻa i nā bits tricone ma mua o nā drill bit ʻē aʻe ʻo ia ka hoʻāʻo o ka manawa. Ua nānā pinepine ʻia lākou e hōʻoia ʻo lākou ka mea maikaʻi loa i ka hoʻokele ʻana i nā kūlana hoʻopunipuni. ʻO ka hiki i nā Tricones ke mālama i nā ʻano palupalu a paʻakikī hoʻi e hāʻawi iā lākou i ka maʻalahi i loaʻa ʻole i nā ʻāpana drill ʻē aʻe.
PDC Bit ma ka ʻOihana ʻAila a me Gas
Loaʻa i nā bits PDC ko lākou inoa mai ka polycrystalline diamond compacts i hoʻohana ʻia no kā lākou ʻoki ʻana. ʻO ka bit PDC he bit drill i hoʻokomo ʻia me nā mea ʻoki daimana ʻoihana ma mua o nā niho metala paʻakikī.
Ua hoʻomohala ʻia nā bits PDC i nā makahiki 1970 a ua lilo i hoʻokahi o nā pahu drill kaulana loa ma ka honua. Hōʻike ka hoʻolālā i nā poʻo paʻa a hana ʻia e ka hui ʻana i nā daimana artificial a me ka tungsten carbide me ka wela a me ke kaomi. ʻOi aku ka wikiwiki o nā bits PDC ma mua o nā bits tricone a maikaʻi loa i ka ʻohi pōhaku, ʻoiai he mau wahi kaʻawale nā ʻāpana tricone a me nā bit PDC i ka ʻoihana wili. ʻO nā hoʻolālā PDC hou loa e pili ana i nā hoʻolālā ʻokiʻoki asymmetric, nā apo ana, a me nā hoʻolālā ʻoki hybrid.
ʻOiai ke kaulana nei nā bits PDC, ke hoʻomau nei nā tricone bits i nā papahana wili like ʻole. ʻO kēia mau mea he ʻiliʻili, dolomite, a me ka limestone paʻakikī. No ka mea ʻaʻole ʻike ka hoʻololi i ka PDC i kahi hoihoi i kēlā mau wahi, e paʻa ana nā tricone bits i kēlā mau kikowaena no ka manawa lōʻihi.
He aha ka ʻokoʻa?
ʻO ka ʻokoʻa maʻalahi loa ma waena o kahi tricone bit a me kahi PDC drill bit ʻaʻole ia he wahi neʻe i ka PDC Bit.
ʻO nā ʻāpana Tricone he ʻekolu mau ʻāpana huila (nā ʻāpana neʻe), a pono lākou i nā bearings lubricated a me kahi waihona momona. Ke hoʻohana ʻia nā tricone bits i nā papahana ʻoi aku ka nui, pono e loaʻa i kahi sila bearing i hiki i nā drillers ke mālama i nā ʻōpala mai ka hoʻokuʻu ʻana i ka hoʻololi ʻana.
Paʻa nā ʻoki ʻoki paʻa PDC a ʻaʻohe ʻāpana neʻe. Hana ʻia nā ʻāpana PDC e ka hui ʻana i nā daimana artificial a me ka tungsten carbide ma lalo o ka wela a me ke kaomi.
ʻOkoʻa ke ʻano ʻoki ʻoki PDC & Tricone. ʻAhi ʻo PDC i ka pōhaku i ka wā e haki ana ka tricone.
Pono ʻo Tricone bit i kahi WOB kiʻekiʻe aʻe e hana maikaʻi. A i ʻole, hiki i kona mau mea hoʻokomo ke pau i ka wā kahiko.
Hōʻuluʻulu manaʻo:
He koho maikaʻi ka PDC bit no kekahi mau kūlana hoʻokumu. Hana maikaʻi nā ʻāpana PDC i ka pōhaku i hoʻohui ʻia, like me ka shale, ke one, ka limestone, ke one, a me ka pālolo. Ke hana ʻoe me nā pōhaku i ʻōlelo ʻia ma luna, hiki iā ʻoe ke hoʻāʻo iā PDC bit ma ke ʻano he wikiwiki, palekana, a me ka hoʻokele waiwai. A i ʻole, ʻo Tricone kāu koho maikaʻi loa.
