Xa kusonjwa amaqula e-oyile kunye nerhasi, ukuqhuba i-casing ukuya ezantsi komngxuma nokufumana umgangatho olungileyo wesamente kubalulekile. I-Casing yityhubhu eyehla kumthombo ukukhusela umthombo ekuweni kunye nokwahlula indawo yokuvelisa kwezinye iifom. I-Casing kufuneka igxininiswe ngokugqibeleleyo kwaye ikhuseleke kwindawo ukuqinisekisa ukusebenza kakuhle kunye nokhuseleko. Kulaphoizinto eziphambiliyiza ekudlaleni.
A izinto eziphambilisisixhobo esinceda ukugcina i-casing isendaweni kwaye igcine isembindini wequla ngexesha lenkqubo yesamente.Centralizerszizinto ezibalulekileyo zezixhobo zokugqitywa kuba ziqinisekisa ukuba i-samente igcwalisa ngokulinganayo i-annulus phakathi kwe-casing kunye nodonga lomthombo, ukudala ibhondi eqinile kunye nokuthintela ukufuduka kwamanzi.
Centralizersbabe ezahlukeneyo zoyilo kunye nezimbo, ukusuka bow spring kunyei-centralizers eqinileukuya kwezintsha, iinguqulelo eziphucukileyo ezifana nezijikelezi-ndawo ezijikelezayo nezingajikeleziyo. Ezi zixhobo zikhethwa ngokwemiqathango yequla kunye neemfuno zesamente. Umzekelo, i-centralizers yenkxaso eqinile ifanelekile kumaqula athe nkqo kunye namaqula athambekele kakhulu anokugoba okuncinci, ngelixa.bow spring centralizerszilungele amaqula athambekeleyo kunye namaqula aneengile ezincinci aneemfuno ezinkulu.
Ukuba i-casing ayigxininisi ngokwaneleyo, i-samente ayiyi kuhanjiswa ngokulinganayo, enokuthi iholele kwi-sheaths ye-cement yendawo okanye imiphumo yomzila. Oku kunokuchaphazela kakubi ukusebenza kwequla kwaye, okona kubaluleke kakhulu, ukhuseleko. Isingxobo sesamente esingaphelelanga sinokubangela ukuba isamente ingasebenzi kwaye ivumele imfuduko yolwelo, ibeke esichengeni isidima sokulunga kunye nokudala iingozi ezinokubakho kokusingqongileyo.
Ukuthintela iingxaki ezinjalo, kunyanzelekile ukuba ukhethe i-centralizer echanekileyo kwaye uqinisekise ukufakela okufanelekileyo. Abanyeizinto eziphambili, ngakumbi iintlobo ezintsha ezijikelezayo kunye nezingajikeleziyo, zibonelela ngokuchaneka okukhulu kokubekwa kunye namanqanaba okusebenza aphezulu kunee-centralizers eziqhelekileyo.
Iindlela ezifanelekileyo zokufakela kufuneka zilandelwe ukufezekisa ukudibanisa okuphezulu phakathi kwe-casing kunye nodonga lomthombo. Ngokulandela ezi zikhokelo, iizinto eziphambiliiyakwazi ukumisa iqula kwaye ibeke indawo ye-casing ngokugqibeleleyo, ibangele umgangatho ophezulu, ovelisayo kwaye ukhuselekile kakuhle.
