ʻO ka hale hana o nā niho wili HDD pilot tricone drill bits ma ke kumukūʻai me ke kumu kūʻai hoʻemi
Wahi wehewehe:
IADC: 517 - TCI i hoʻopaʻa ʻia i ka bit bearing bit me ka pale ana no nā ʻano palupalu palupalu a me ka haʻahaʻa me ka ikaika compressive haʻahaʻa.
Ka ikaika compressive:
85 - 100 MPA
12,000 - 14,500 PSI
Ka wehewehe ʻāina:
ʻO nā pōhaku ʻoʻoleʻa a me nā pōhaku paʻa e like me ke one me nā ʻōniʻoniʻo o ka quartz, ka limestone paʻakikī a i ʻole ka chert, hematite ores, paʻakikī, paʻa maikaʻi ʻia nā pōhaku abrasive e like me: nā pōhaku one me ka quartz binder, dolomites, quartzite shales, magma a me ka metamorphic coarse grained pōhaku.
Hiki i ka Far Eastern Drilling ke hāʻawi i nā bits tricone HDD i nā ʻano nui (mai 3" a 26") a me ka hapa nui o nā Codes IADC.
