Isishwankathelo
Intloko yebhokisi lelona candelo libalulekileyo kwimithombo yeoli nerhasi, emi phakathi kwebhokisi kunye nesixhobo somthombo. Isebenza imisebenzi emininzi engundoqo, kuquka ukudibanisa iileya ezahlukeneyo ze-casing, ukudibanisa i-casing kwisithinteli sokuvuthela, kunye nokubonelela ngenkxaso kunye nokudibanisa kwentloko yomthombo emva kokugqitywa kakuhle. Uyilo lwayo luyimfuneko ekugcineni uzinzo lwe-wellhead, ukuqinisekisa ukutywinwa okusebenzayo, kunye nokuxhasa uluhlu lwemisebenzi yokomba kunye nemveliso.
Ulwakhiwo kunye noQhagamshelwano
- Uxhulumaniso olusezantsi: Isiphelo esisezantsi sentloko ye-casing ifakwe kwintambo ukuze idibanise ngokukhuselekileyo kwi-surface casing, inikezela isiseko esizinzile.
- Uxhulumaniso oluPhezulu: Isiphelo esiphezulu sidibanisa nesixhobo somthombo okanye isithinteli sokuvuthela ngeeflange okanye i-clamps, iququzelele ukufakela ngokufanelekileyo kunye nokudibanisa kunye nala macandelo.
- I-Hanger: I-hanger isekela ubunzima bemigangatho ye-casing elandelayo kwaye ithwala umthwalo wokuthintela ukuvuthela, ukuqinisekisa ukuba inkqubo ye-wellhead ihlala izinzile.
Imisebenzi ephambili
- Inkxaso kunye nokuThuthwa koMthwalo:
- Inkxaso: Isixhobo sokuxhoma sentloko ye-casing isekela ubunzima bazo zonke iileyile ze-casing ngaphaya kwe-surface casing, iqinisekisa ukunyaniseka kwesakhiwo somthombo.
- Ukuthwala Umthwalo: Ihambisa ubunzima bendibano yokuthintela ukuvuthela, ukugcina ukuzinza ngokubanzi kwenkqubo ye-wellhead.
- Ukutywinwa:
- Ibonelela ngoxinzelelo olusebenzayo lokutywinwa phakathi kwe-casings yangaphakathi nangaphandle ukuthintela ukuvuza kwamanzi kwintloko yomthombo.
- Uhlangulo loxinzelelo:
- Inika indawo yokuphuma yokukhulula naluphi na uxinzelelo olunokuthi lwakheke phakathi kweekholamu zecasing. Kwiimeko ezingxamisekileyo, ulwelo olunjengokubulala ulwelo lokomba, amanzi, okanye ii-arhente zokucima umlilo ezisebenza ngokufanelekileyo zinokumpontshelwa equleni ukuzinzisa uxinzelelo.
- Inkxaso yeMisebenzi eYodwa:
- Ivumela ukomba olukhethekileyo kunye nemisebenzi yokuvelisa, efana nokutofa isamente kwimingxunya esecaleni ukukhulisa ingqibelelo yecasing, okanye ukufaka uxinzelelo kwimingxunya esecaleni ngexesha leasidi okanye ukwaphuka ukulawula uxinzelelo ngaphakathi kwetyhubhu.
Iimbonakalo
- Iindlela zoQhagamshelwano: Intloko ye-casing ibamba zombini i-threaded kunye ne-clamp uqhagamshelo, inikezela ngeendlela eziguquguqukayo kunye nezisebenzayo zokufakela ukunqunyanyiswa kwe-casing ngokukhawuleza.
- Ulwakhiwo lokutywina: Isebenzisa isakhelo esidityanisiweyo sokutywina esidibanisa izinto eziqinileyo kunye nerubha, kunye nezitywina ezikhethiweyo zentsimbi ezifumanekayo ukomeleza uthintelo lokuvuza kunye nokusebenza kokutywina.
- Gqoka i-Sleeves kunye neZixhobo zoVavanyo loxinzelelo: Kubandakanya ukunxiba imikhono kunye nezixhobo zokuvavanya uxinzelelo ezenzelwe ukususwa ngokulula kwemikhono yokunxiba kunye nokuqhuba iimvavanyo zoxinzelelo kwintloko ye-casing.
- Uyilo oluPhezulu lweFlange: I-flange ephezulu ixhotyiswe ngovavanyo loxinzelelo kunye nezixhobo ze-injection yegrisi yesibini, ukuphucula ukusebenza ngokulula kunye nokhuseleko.
- Ukucwangciswa kweValve ye-Side Wing: Intloko ye-casing inokufakelwa iivalve zecala ezisekelwe kwiinkcukacha zomsebenzisi ukujongana neemfuno ezahlukeneyo zokusebenza.
Isishwankathelo
Intloko ye-casing yinto ebalulekileyo kwimithombo yeoli kunye negesi, kunye noyilo lwayo kunye nokusebenza okuchaphazela kakhulu ukuzinza, ukutywinwa, kunye nokusebenza kakuhle kokomba kunye nokusebenza kwemveliso. Ngokubonelela ngenkxaso ebalulekileyo, ukutywinwa okusebenzayo, ukunciphisa uxinzelelo, kunye nenkxaso yemisebenzi ekhethekileyo, intloko ye-casing idlala indima ebalulekileyo kwinkqubo yokukhutshwa kweoli kunye negesi.
