Houston, Texas - Ua hana nā mea noiʻi ma kahi hui ʻenehana aila a me ka ʻenehana i kahi holomua nui i ka hoʻomohala ʻana i nā mea ʻoki PDC. ʻO nā mea ʻokiʻoki polycrystalline diamond compact (PDC) nā mea koʻikoʻi o nā bit drill i hoʻohana ʻia i ka ʻimi ʻaila a me ke kinoea a me ka hana ʻana. Hana ʻia lākou i kahi ʻāpana lahilahi o nā kristal daimana ʻoihana i hoʻopaʻa ʻia i kahi substrate tungsten carbide. Hoʻohana ʻia nā mea ʻoki PDC no ka ʻoki ʻana i nā ʻano pōhaku paʻakikī no ke komo ʻana i nā mālama aila a me ke kinoea.
ʻO nā mea ʻokiʻoki PDC hou i hoʻomohala ʻia e nā mea noiʻi he ʻoi aku ka ʻoi aku o ka pale lole ma mua o nā mea ʻoki PDC i loaʻa. Ua hoʻohana ka poʻe noiʻi i kahi ala hou o ka synthesizing i nā kristal daimana i hana i nā mea ʻokiʻoki, kahi i loaʻa ai ka ʻoki ʻoi aku ka lōʻihi a lōʻihi.
"ʻO kā mākou mau meaʻoki PDC hou he pale lole iʻekolu manawa kiʻekiʻe ma mua o nā meaʻoki PDC i loaʻa," wahi a Dr. Sarah Johnson, ka mea noiʻi alakaʻi ma ka papahana. "ʻO ia ke ʻano o ka lōʻihi o ka lōʻihi a koi ʻia ka hoʻololi pinepine ʻana, e hopena i ka mālama kālā nui no kā mākou mea kūʻai."
ʻO ka hoʻomohala ʻana i nā mea ʻokiʻoki PDC hou he mea koʻikoʻi nui ia no ka ʻoihana ʻaila a me ke kinoea, e hilinaʻi nui nei i ka ʻenehana wili no ke komo ʻana i nā mālama aila a me ke kinoea. ʻO ke kumukūʻai o ka wili ʻana hiki ke lilo i mea pale nui i ke komo ʻana i ka ʻoihana, a ʻo nā holomua ʻenehana e hōʻemi i nā kumukūʻai a hoʻonui i ka pono e ʻimi nui ʻia.
"ʻO kā mākou mau meaʻoki PDC hou e hiki ai i kā mākou mea kūʻai ke wili i ka ʻoi aku ka maikaʻi a me ke kumu kūʻai haʻahaʻa," i ʻōlelo ai ʻo Tom Smith, Luna Nui o ka ʻoihana ʻenehana aila a me ke kinoea. "ʻO kēia ka mea e hiki ai iā lākou ke komo i ka ʻaila aila a me ke kinoea i hiki ʻole ke loaʻa mua a hoʻonui i kā lākou loaʻa kālā."
ʻO ka hoʻomohala ʻana i nā mea ʻoki PDC hou he hoʻoikaika like ʻana ma waena o ka hui ʻenehana aila a me ke kinoea a me kekahi mau kula nui. Ua hoʻohana ka hui noiʻi i nā ʻenehana ʻepekema waiwai holomua e synthesize i nā kristal daimana i hana i nā mea ʻoki. Ua hoʻohana pū ka hui i nā mea hana hou e hoʻāʻo ai i ke kūpaʻa a me ka lōʻihi o nā mea ʻoki hou.
Aia nā mea ʻoki PDC hou i nā pae hope loa o ka hoʻomohala ʻana, a ke manaʻo nei ka ʻoihana ʻenehana aila a me ke kinoea e hoʻomaka e hana i nā mea nui ma hope o kēia makahiki. Ua loaʻa mua i ka hui ka hoihoi nui mai kāna mau mea kūʻai aku, a ke manaʻo nei ʻo ia e kiʻekiʻe ka koi no nā mea ʻoki hou.
ʻO ka hoʻomohala ʻana i nā mea ʻoki PDC hou he laʻana o ka hana hou i ka ʻoihana ʻaila a me ka ʻenehana. Ke hoʻomau nei ka noi no ka ikehu, pono ka ʻoihana e hoʻomau i ka hoʻomohala ʻana i nā ʻenehana hou e hiki ai ke komo i nā waihona aila a me nā kinoea. ʻO nā mea ʻoki PDC hou i hoʻomohala ʻia e ka hui ʻenehana aila a me ka ʻenehana he mea hoʻomohala hoihoi e kōkua i ka hoʻokele ʻana i ka ʻoihana i mua.
