Mea hoʻolako ʻia nā pahu wili wili API IADC216 5 3/4 iniha (146mm)
Hōʻike huahana
Kuʻuna hana
2) Ka hoʻololi ʻana o ka pahu drill I ka wā e hoʻololi ai ka drill bit, ua kapa ʻia ka huli ʻana o ka conearound i ke koʻi o ka poho niho. Hoʻoholo ʻia ka wikiwiki o ka hoʻololi ʻana o ka cone e ka wikiwiki kipi o ka drill bit, a pili i ka hopena o nā niho ma lalo o ka luawai.
3) ʻO ka vibration longitudinal (axial vibration) ka hopena o ka haʻihaʻi ʻana o ka drill bit ʻO ka hoʻololi ʻana o ke kūlana o ke kikowaena huila e hoʻihoʻi i ka drill bit i luna a i lalo ma ke ala axial, ʻo ia ka haʻalulu longitudinal o ka drill bit, e pili ana i nā ʻāpana hoʻolālā drill bit e like me ke kiʻekiʻe o ka niho a me ka spacing niho a me ka lithology. He liʻiliʻi nā ʻāpana palupalu, ʻo nā ʻāpana paʻakikī he mau amplitudes nui. Ua like ka vibration frequency i ka helu o nā niho a me ka wikiwiki o ka cone.
Hoʻoholo ʻia e nā ʻāpana hoʻolālā o ka drill bit. Ma nā ʻano palupalu, nui ka paheʻe bit, a ma nā ʻano paʻakikī, ʻo ia
e liʻiliʻi a paheʻe paha.

5 3/4 "TCI tricone bit ua hoʻohana nui ʻia i ka ʻeli wai punawai, ka ʻimi ʻana, ka lua hoʻokele HDD, ka hoʻokumu ʻana i ke kahua, aia kahi hoʻolālā jet hole waena, no laila hiki ke hoʻohana ʻia no ka hoʻohuli ʻana i ka wili. ʻoi aku ka lōʻihi o ke ola ma mua o nā ʻāpana huila hāmama.
