Ke poʻo kaʻa no ka rig IADC127 9 7/8 ” (250.8mm)
Hōʻike huahana
Ua kūkulu ka Far Eastern Drilling i kahi tricone bit kiʻekiʻe, roller cone bit, hole opener a me PDC bit production line me ka ʻenehana holomua, nā lako piha a me ka hoʻokele maʻamau. a ua hana ʻia ka drill bit PDC ma kahi ʻano nui.Hana ʻia kēlā me kēia huahana a nānā ʻia e like me nā kūlana ʻenehana kiʻekiʻe o ka ʻoihana a me nā kikoʻī API.ʻO ka ʻōnaehana hōʻoia maikaʻi i hoʻokumu ʻia e like me nā koi o ISO 9001 a me API e hōʻoia i ka maikaʻi o nā huahana a me ka hana pono o ka ʻoihana.

ʻO ka pōmaikaʻi o ka bit tricone niho kila:
1> ʻoi aku ka nui o ke komo ʻana.ʻOi aku ka wikiwiki o ka ʻeli ʻana i lalo o nā niho lōʻihi.
2>Ai-popopo.ʻO nā pōhaku paʻa e hana mau ana i ka bit-balling, kūpono ka bit tricone bit no ka wili ʻana i nā mea palupalu a me nā pōhaku pili.
3> IADC127 he tungsten carbide inserts ma ka ana o cones, keia hiʻona mea pono e pale anawaena-shrinkage.
