E hoʻololi i ka wai drill i loko o ke kaula drill
ʻO ka drilling Swivel ka mea nui no ka rotary circulation o ka hana ma lalo o ka honua. ʻO ia ka pilina ma waena o ka ʻōnaehana hoʻi a me ka mea hana wili, a me ka ʻāpana pili ma waena o ka ʻōnaehana kaʻa a me ka ʻōnaehana wili. ʻO ka ʻaoʻao luna o ka Swivel e kau ʻia ma luna o ka makau ma o ka loulou elevator, a ua hoʻopili ʻia i ka hose wili e ka paipu gooseneck. Hoʻopili ʻia ka ʻaoʻao haʻahaʻa me ka paipu drill a me ka mea hana hoʻoheheʻe downhole, a hiki ke holo i luna a i lalo me ka poloka huakaʻi.
ʻO ka mea mua, nā koi o nā faucet wili no nā hana ma lalo o ka honua
1. ʻO ke kuleana o nā faucet wili
(1) Hoʻokuʻu ʻia nā mea hana wili no ke kū ʻana i ke kaumaha piha o nā mea hana wili lalo.
(2) E hōʻoia i ka manuahi o ka puʻu haʻahaʻa no ka hoʻololi ʻana a ʻaʻole paʻa ka hui luna o ke kelly.
(3) Hoʻopili ʻia i ka ʻauʻau wili no ka paila ʻana i ka wai kaomi kiʻekiʻe i loko o ka paipu wiliwili e ʻike ai i ka wili ʻana.
Hiki ke ʻike ʻia e hiki ke hoʻomaopopo i ka faucet drilling i nā hana ʻekolu o ka hāpai ʻana, ka hoʻololi ʻana a me ke kahe ʻana, a he mea nui ia o ka rotation.
2. Nā koi no ka wili ʻana i nā faucets i nā hana downhole
(1) Pono e lawa ka ikaika o nā mea lawe nui o ka puʻu wili, e like me ke apo hāpai, ka paipu waena, ka halihali ukana, a me nā mea ʻē aʻe.
(2) Pono e loaʻa i ka ʻōnaehana hoʻopaʻa ʻana o ka flushing assembly sealing i nā waiwai kiʻekiʻe, ʻaʻahu a me ka corrosion, a he mea maʻalahi ke hoʻololi i nā ʻāpana ʻino.
(3) Pono e hoʻopaʻa maikaʻi ʻia ka ʻōnaehana hoʻopaʻa ʻaila haʻahaʻa haʻahaʻa, pale i ka corrosion a lōʻihi ke ola lawelawe.
(4) Pono ke ʻano a me ke ʻano o ka faucet wīwī a maʻemaʻe a me ka angular, a ʻo ke koʻi koʻi o ke apo hāpai e kūpono no ke kau ʻana i nā makau.
Nā hiʻohiʻona ʻenehana:
• Me ke koho paʻi pālua ʻāpana kila sub.
• 'O ka paipu holoi a me ka pa'i pahu he mau hale ho'ohui 'ano pahu a ma'alahi ke ho'ololi.
• Hoʻohui ʻia ka gooseneck a me ka hose rotary e nā uniona a i ʻole API 4LP.
