ʻO nā paipu drill a me nā kola drill he mau mea hana koʻikoʻi i ka ʻoihana ʻaila. E hōʻike ana kēia ʻatikala i nā ʻokoʻa ma waena o kēia mau huahana ʻelua.

Nā Kola wili

Aia nā kola wili ma lalo o ke kaula drill a he mea nui ia o ka hui puka lalo (BHA). ʻO kā lākou mau hiʻohiʻona nui ko lākou mau paia mānoanoa (maʻamau 38-53mm, ʻo ia ka 4-6 mau manawa ʻoi aku ka mānoanoa ma mua o nā paia o nā paipu drill), e hāʻawi ana i ke kaumaha nui a me ka rigidity. No ka hoʻomaʻamaʻa ʻana i nā hana wili, hiki ke hoʻohana ʻia i nā ʻauwaʻa hāpai a me nā ʻauwaha paheʻe ma luna o ka ʻili o waho o nā kaula kūloko o ka drill collar.

Paipu wili

ʻO nā paipu wili he mau paipu kila me nā wēlau wili, i hoʻohana ʻia e hoʻopili i nā mea hana ili o ka rig wili me nā mea wili a i ʻole ka hui lua lalo ma lalo o ka luawai. ʻO ke kumu o nā paipu drill ʻo ia ka lawe ʻana i ka lepo wili i ka bit drill a me ka hana pū me ka drill bit e hoʻokiʻekiʻe, hoʻohaʻahaʻa, a hoʻohuli paha i ka hui lua lalo. Pono nā paipu Drill e kū i nā kaomi nui o loko a me waho, torsion, kulou, a me ka haʻalulu. I ka wā o ka ʻaila a me ka ʻea a me ka hoʻomaʻemaʻe ʻana, hiki ke hoʻohana hou ʻia nā paipu drill i nā manawa he nui. Hoʻokaʻawale ʻia nā paipu wili i loko o nā paipu wili square, pipe drill maʻamau, a me nā paipu wili kaumaha.

Nā Hana like ʻole i ka ʻaila ʻaila a me ke kinoea
Hoʻohana ʻia kēia mau mea hana ʻelua i nā kumu like ʻole i ka ʻili ʻaila a me ke kinoea. ʻO nā kola wili he mau paipu kila mānoanoa i hoʻohana mua ʻia e hoʻohui i ke kaumaha i ke kaula drill, e hāʻawi ana i ke kaomi drill nui aʻe a pale i ka hoʻokaʻawale maikaʻi. ʻO nā paipu Drill, ma ka ʻaoʻao ʻē aʻe, he mau paipu kila ʻili lahilahi i hoʻohana mua ʻia e hoʻouna i ka torque a me ka wai wili e hiki ai ke hoʻololi a me ka wili ʻana o ka drill bit.

I ka hōʻuluʻulu ʻana, hāʻawi nā kola drill, me ko lākou kaumaha nui a me ka ʻoʻoleʻa, hāʻawi i ke kaumaha hou a me ke kūpaʻa i ke kaula drill, ʻoiai nā paipu drill ke kuleana no ka hoʻouna ʻana i ka mana mechanical a me ka lawe ʻana i ka lepo wili. Hana pū kēia mau mea hana ʻelua e hōʻoia i ka holo mālie o nā hana wili.
