Ho Utloisisa Mesebetsi ea Likopano Tsa Casing Head ho Wellhead Equipment

Ts'ebetsong ea liliba tsa oli le khase,likopano tsa casing headphetha karolo ea bohlokoa ho netefatsa polokeho le katleho ea ts'ebetso ea tlhahiso. Karolo ena ea bohlokoa ealisebelisoa tsa hantlee etselitsoe ho fana ka tšehetso bakeng sa khoele ea casing le ho tiisa annulus pakeng tsa casing le seliba. Ho utloisisa hore na joangkopano ea hlooho ea casingmosebetsi o bohlokoa ho mang kapa mang indastering ea oli le khase.

 Kopano ea hlooho ea casinghangata e kenngoa ka holim'a mokotla oa seliba 'me e sebetsa e le sebaka sa ho hokahanya likarolo tse fapaneng tsa lisebelisoa tsa seliba. E na le likarolo tse 'maloa tsa bohlokoa, ho kenyelletsa hlooho ea casing, casing spool le casing hanger. Hlooho ea casing ke karolo e kholo, e boima e bolted ka holim'a mokotla oa seliba. E fana ka bolulo bakeng sa spool ea casing 'me e sebetsa e le tšehetso bakeng sa boima ba khoele ea casing.

Ka lehlakoreng le leng, casing spool ke sesebelisoa sa cylindrical se bolted ka holimo ho hlooho ea casing. E fana ka mokhoa oa ho boloka hanger ea casing le ho theha tiiso pakeng tsa casing le seliba. The casing hanger ke karolo ea bohlokoa e tšehetsang boima ba khoele ea casing le ho fana ka tiiso ho thibela maro a tsoang selibeng.

E 'ngoe ea mesebetsi e ka sehloohong ea kopano ea hlooho ea casing ke ho fana ka khokahanyo e sireletsehileng le e ka tšeptjoang pakeng tsa khoele ea casing le seliba. Khokahano ena e bohlokoa ho boloka botsitso ba seliba le ho thibela ho lutla ha oli, khase ea tlhaho kapa maro a mang. Kopano ea hlooho ea casing e boetse e fana ka mokhoa oa ho emisa khoele ea casing ka har'a seliba 'me e lumella ho kenngoa ha likarolo tse ling tsa bohlokoa tse kang lithibelo tsa ho folisa le lifate tsa tlhahiso.

Ntle le ho fana ka tšehetso bakeng sa khoele ea casing, kopano ea hlooho ea casing e boetse e phetha karolo ea bohlokoa ts'ebetsong ea samente. Ka mor'a hore khoele ea casing e kenngoe, samente e pompeloa ka har'a annulus pakeng tsa casing le seliba ho theha mokoallo oa tšireletso le ho thibela maro a tsoang ho falla pakeng tsa libopeho tse fapaneng tsa jeoloji. Kopano ea hlooho ea casing e fana ka mokhoa oa ho kenya slurry ea samente ka har'a annulus le ho etsa bonnete ba hore slurry ea samente e ajoa ka ho lekana ho potoloha khoele ea casing.

Ho feta moo,likopano tsa casing headli etselitsoe ho kenya letsoho ho kenngoeng ha mefuta e fapaneng ea lisebelisoa tsa hlooho, joalo ka li-valve, chokes, le li-gauge tsa khatello. Likarolo tsena li bohlokoa bakeng sa ho laola phallo ea maro a seliba le ho hlokomela khatello ea metsi le maemo a mocheso. Kopano ea hlooho ea casing e fana ka sebaka se sireletsehileng le se fumanehang bakeng sa ho kenngoa ha thepa ena, e leng se lumellang hore ho be le ts'ebetso e sireletsehileng le e sebetsang hantle ea seliba.

Ho akaretsa, kopano ea hlooho ea casing ke karolo ea bohlokoa ea lisebelisoa tsa hantle 'me e phetha karolo ea bohlokoa ts'ebetsong e bolokehileng le e sebetsang ea liliba tsa oli le khase. Likopano tsa lihlooho tsa casing li netefatsa bots'epehi le tlhahiso ka ho fana ka ts'ehetso bakeng sa khoele ea casing, ho theha tiiso pakeng tsa casing le wellhead, le ho kenya letsoho ho kenya lisebelisoa tsa bohlokoa tsa seliba. Ho utloisisa hore na likopano tsa casing head li sebetsa joang ho bohlokoa ho mang kapa mang ea amehang moralong, kahong kapa ts'ebetsong ea liliba tsa oli le khase.
