Lapho ushayela uwoyela kanye nemithombo yegesi, egijima i-casing ezansi komgodi nokuthola ikhwalithi enhle kasimende kubalulekile. I-Casing yi-tubing egijimisa kahle i-Wellbore ukuvikela i-Wellbore kusuka ekuweni nasekuhlukaniseni indawo yokukhiqiza kusuka kwezinye izindlela. I-Casing kumele igxile ngokuphelele futhi ivikelwe endaweni yokuqinisekisa ukusebenza kahle nokuphepha okuhle. Yilaphoabaphakathiazodlalwa.
A abaphakathiIngabe idivaysi esiza ukugcina ama-casing endaweni futhi igcina igxile ku-borehole ngesikhathi senqubo yokumemela.Abaphakathiziyizakhi ezibucayi zemishini yokuqeda ngoba ziqinisekisa ukuthi usimende ugcwalisa ngokulinganayo i-annulus phakathi kwe-casing kanye nodonga oluqinile, ukudala isibopho esiqinile nokuvimbela ukufuduka okunamandla.
Abaphakathiube nemiklamo ehlukahlukene nezitayela, kusuka emnsalweni wentwasahlobo futhiabasebenza kanzimakuya ezinguqulweni ezintsha, ezithuthukile ezifana nokujikeleza nokujikeleza okungaguquki. Lawa madivayisi akhethiwe ngokuya ngezimo ezinhle kanye nezidingo zokonga. Isibonelo, abasebenza ngokusekelwa okuqinile balungele imithombo emile mpo nemithombo ethambekele kakhulu ngokugoba okuncane, ngenkathiBow Spring CunterZilungele imithombo ethambekele nemithombo embizelele ama-angles ngezidingo ezinkulu.
Uma i-casing ingagxiliswe ngokwanele, usimende ngeke asatshalaliswe ngokulinganayo, okungaholela emigodini ye-centment yasendaweni noma imiphumela yokuhlela. Lokhu kungathinta kabi ukusebenza komthombo futhi, okubaluleke kakhulu, ukuphepha. I-sheath ye-cemential eyingxenye ingadala usimende ukuze yehluleke futhi ivumele ukufuduka kwamanzi, ukuyekethisa ubuqotho kanye nokwakha izingozi ezingaba khona zemvelo.
Ukuvimbela izinkinga ezinjalo, kubalulekile ukukhetha i-cestizer efanele futhi uqinisekise ukufakwa okufanele. -Nyeabaphakathi, ikakhulukazi izinhlobo ezintsha ezijikelezayo nezingaguquli, nikeza ukunemba okukhulu kakhulu kanye namazinga okusebenza aphezulu kunamazinga endabuko.
Amasu wokufaka okufanele kufanele alandelwe ukuze afinyelele ukuxhumana okuphezulu phakathi kweCasing kanye nodonga olunzulu. Ngokulandela le mihlahlandlela,abaphakathiingabeka kahle umthombo futhi igxile e-casing ngokuphelele, okuholela ekutheni ikhwalithi ephezulu, ikhiqize futhi iphephile kahle.
