Hale hana o nā ʻāpana wili HDD pilot tricone niho wili ʻia i loko o ka waihona me ke kumu kūʻai hoʻēmi
Wehewehe ʻana o ka Bit:
IADC: 517 - ʻO ka bit bearing i hoʻopaʻa ʻia me ka puke pai TCI me ka pale gauge no nā ʻano palupalu a waena me ka ikaika compressive haʻahaʻa.
Ikaika Hoʻopaʻa:
85 - 100 MPA
12,000 - 14,500 PSI
Wehewehe ʻĀina:
Nā pōhaku paʻakikī waena a me nā pōhaku ʻāpala e like me nā one one me nā kaha o ka quartz, ka pōhaku limestone paʻakikī a i ʻole ka chert, nā ʻonika hematite, nā pōhaku abrasive paʻakikī, i hoʻopaʻa maikaʻi ʻia e like me: nā one one me ka mea hoʻopaʻa quartz, nā dolomites, nā shales quartzite, ka magma a me nā pōhaku metamorphic coarse grained.
Hiki iā Far Eastern Drilling ke hāʻawi i nā ʻāpana tricone HDD i nā nui like ʻole (mai 3” a 26”) a me ka hapa nui o nā code IADC.
