ʻO nā pōmaikaʻi o nā bits PDC

Ua hoʻolauna ʻia nā ʻāpana drill polycrystalline diamond compact (PDC) a me PDC i ka mākeke no kekahi mau makahiki. Iloko o keia manawa loihi,ka PDC cutter a me ka PDC drill bit ua loaʻa i nā pilikia he nui i ko lākou wā mua, ua ʻike pū kekahi i ka hoʻomohala nui. Me ka lohi akā i ka hope, ua hoʻololi mālie nā ʻāpana PDC i nā ʻāpana cone me ka hoʻomaikaʻi mau ʻana i ka ʻoki PDC, ka paʻa paʻa, a me ke ʻano hydraulic bit. Noho ʻia nā bits PDC ma mua o 90% o ka nui o nā kiʻi wili i ka honua.

Hoʻohana ʻia ka bit drill diamond ma kahi kokoke i nā noi āpau e like me ka ʻeli ʻana i ka ikehu geothermal, ka ʻeli ʻana, ka lua wai, ka ʻeli kinoea maoli, a me ka ʻeli ʻana o ka ʻaila.

Eia kekahi mau pono o nā bits PDC.

1. Ke kumu kūʻai

Hiki ke kūʻai nui ʻia nā bits PDC. ʻAʻole liketricone bit, ʻaʻohe ʻāpana neʻe i ka bit PDC e luhi. Hiki i ke daimana synthetic ke alo, akā hiki ke unuhi ʻia kēlā mea ʻoki PDC a hiki ke hoʻokomo i kahi mea hou ma kona wahi. ʻO ke kūkulu hou ʻana i kahi bit PDC ma kahi o ka hapalua o ke kumukūʻai o ke kūʻai ʻana i kahi bit hou.

2. Laki o ke komo ana

ʻO nā ʻāpana PDC, i nā hoʻokumu kūpono, loaʻa kahi helu nui o ke komo ʻana. ʻO nā hana i hana maikaʻi ʻia e nā bits PDC akā ʻaʻole i kaupalena ʻia i ka shale, ka limestone, ka pōhaku one, a me ka pālolo. Hiki i nā ʻāpana PDC ma kahi o 3-5 mau manawa ʻoi aku ka wikiwiki ma mua o nā ʻāpana tri-cone.

3. Hoʻokohu kālā

Mālama nā PDC i ke kālā. No ka mea ʻoi aku ka wikiwiki o ka puʻu ʻana o nā bits PDC, nui ka manawa i mālama ʻia. Mālama ka manawa i hiki i ka driller ke hoʻopau i nā hana hou aku i kahi manawa pōkole. Ma kahi hana liʻiliʻi, mālama ʻia nā hola a me nā lā. Ma kahi ʻoihana nui, he mau pule a me nā mahina i mālama ʻia. ʻO nā pōmaikaʻi o ka hoʻopau wikiwiki ʻana i ka hana, ʻo ia ka mālama ʻana i nā hola kanaka a me ka wahie, hālāwai a/a ʻoi aku paha i nā manawa palena, a me ka hoʻohana ʻana i nā mea liʻiliʻi a me nā mea hoʻohana.

Ma ke ʻano holoʻokoʻa, nui nā pōmaikaʻi o ka ʻeli ʻana me nā bits PDC. E like me nā mea a pau, ke loli mau nei ka ʻoihana wili. Hiki ke hoʻololi i ka ʻenehana a me ka wili ʻana i mea maikaʻi. Hiki i nā ʻāpana PDC ke hoʻololi i ka ʻokoʻa iā ʻoe.
