I ka ʻeli ʻana i nā luawai aila a me ke kinoea, ʻo ka holo ʻana i ka pahu i lalo o ka lua a loaʻa ka maikaʻi sima maikaʻi. ʻO Casing ka paipu e kahe ana i lalo o ka luawai no ka pale ʻana i ka luawai mai ka hāʻule ʻana a e hoʻokaʻawale i ka ʻāpana hana mai nā ʻano hana ʻē aʻe. Pono e hoʻonohonoho pono ʻia ka pahu pahu a paʻa i kahi e hōʻoia ai i ka hana maikaʻi a me ka palekana. ʻO kēia kahinā mea kikowaenahele mai i ka pāʻani.
A nā mea kikowaenaHe mea ia e kōkua ai i ka hoʻopaʻa ʻana i ka pahu a hoʻopaʻa i ke kikowaena i loko o ka lua i ka wā o ke kaʻina hana sima.CentralizersHe mau mea koʻikoʻi ia o nā mea hana hoʻopau no ka mea e hōʻoia lākou i ka hoʻopiha piha ʻana o ka sima i ka annulus ma waena o ka pahu a me ka pā punawai, e hana ana i kahi paʻa ikaika a pale i ka neʻe ʻana o ka wai.
Centralizersloaʻa nā ʻano hoʻolālā a me nā ʻano like ʻole, mai ka puna kakaka a menā mea kikowaena paʻai nā mana hou, ʻoi aku ka holomua e like me ka rotating a me ka non-rotating centralizers. Ua koho ʻia kēia mau mea e like me nā kūlana maikaʻi a me nā koi cementing. No ka laʻana, kūpono nā mea kikowaena kākoʻo paʻa no nā pūnāwai kū pololei a me nā pūnāwai kūwili me ka liʻiliʻi liʻiliʻi, ʻoiaibow spring centralizerskūpono no nā pūnāwai inclined a me nā pūnāwai liʻiliʻi me nā koi nui aʻe.
Inā ʻaʻole lawa ka paʻa ʻana o ka pahu, ʻaʻole e māhele like ʻia ka sima, hiki ke alakaʻi i nā sheaths ciment localized a i ʻole nā hopena channeling. Hiki i kēia ke hoʻopilikia i ka hana o ka pūnāwai a, ʻoi aku ka mea nui, palekana. Hiki i ka puʻu sima ʻāpana ke hoʻopau i ka sima a ʻae i ka neʻe ʻana o ka wai, e hōʻemi ana i ka pono kūpono a me ka hana ʻana i nā pōʻino kaiapuni.
No ka pale ʻana i kēlā mau pilikia, pono ia e koho i ka centralizer kūpono a hōʻoia i ka hoʻonohonoho pono ʻana. ʻO kekahinā mea kikowaena, ʻoi aku ka ʻoi aku o nā ʻano hoʻololi hou a me nā ʻano hoʻololi ʻole, hāʻawi i ka pololei o ka waiho ʻana a me nā pae hana kiʻekiʻe aʻe ma mua o nā kikowaena kuʻuna.
Pono e hahai ʻia nā ʻenehana hoʻonohonoho kūpono no ka loaʻa ʻana o ka pilina kiʻekiʻe ma waena o ka pahu a me ka pā punawai. Ma ka hahai ʻana i kēia mau alakaʻi, ʻo kanā mea kikowaenahiki iā ia ke hoʻopaʻa i ka pūnāwai a hoʻokomo pono i ka pahu, e hopena i ka maikaʻi kiʻekiʻe, huahua a palekana.
