Xa kufikwa kuizinto eziphambili, amandla, ukuguquguquka kunye nokuthembeka kubaluleke kakhulu. Kwizicelo ezicela umngeni ngakumbi apho imveliso yesiqwenga esinye ihlala ifuneka,ihinge centralizersibe lukhetho lokuqala. Ilungiselelwe ngokukodwa ukuhlangabezana neemfuno zoxinzelelo oluphezulu kunye neemeko ezicela umngeni, ezi zinto ziphakathi zibonelela ngokuguquguquka okuphezulu kunye nokuthembeka ekusebenzeni okusebenzayo komthombo.
Olunye uhlobo lokuvakalisaisiphakathioko kubalaseleyo kwimarike kukucacisabow spring centralizer. Eyaziwayo ngokwakhiwa komgangatho ophezulu, le centralizer ibonelela ngokusebenza okungafaniyo kwizicelo ezahlukeneyo, kubandakanywa ne-onshore, i-offshore, i-deepwater kunye namaqula atenxe kakhulu.
Ukucacisabow spring centralizersziyilelwe ukubonelela ngokuguquguquka okuphezulu ngaphandle kokubeka esichengeni ukuqina. Ulwakhiwo lwayo olunehenjisi luyenza ilungele imigodi engathanga ngqo. Oku kuguquguquka kuqinisekisa i-casing kubunzulu obufunwayo, ikhuthaza i-cementing esebenzayo kunye nokunciphisa umngcipheko womonakalo wokwakheka.
Ukongeza ekubeni bhetyebhetye,ihenjisi bow spring centralizersiqinisekisa ukubayayoinokudlula ngokulula kwimiqobo kunye nemingxuma emxinwa ngexesha lofakelo. Amandla okuqalisa acuthiweyo nawo aququzelela ukusebenza ngokufanelekileyo kwecasing kwaye anciphise ithuba lokuncamathela kwecasing njengoko ithotywa umngxuma ongezantsi.
Olunye uphawu oluphambili lokuthethabow spring centralizersngamandla abo aphezulu okubuyisela. I-centerizer iyakwazi ukusebenzisa amandla aqinileyo kuxinzelelo, iqinisekisa ukucoceka okulungileyo, ukuphucula ukufuduswa kwesamente kunye nokukhuthaza ingqibelelo kakuhle. Amandla okubuyisela awandisiweyo akwaqinisekisa ukuba i-casing igxile ngokufanelekileyo kumthombo, ukunciphisa intshukumo ye-annular fluid, ngaloo ndlela kuncitshiswa umngcipheko wokuhamba kunye nokwahlukaniswa kwendawo.
Ihingedbow spring centralizerszenzelwe ukugqwesa kwizicelo ezicela umngeni apho amandla kunye nokuthembeka kubaluleke kakhulu. Ukwakhiwa kwayo okuqinileyo kunye nezinto ezisemgangathweni ophezulu zivumela ukuba zimelane neemeko ezinzima ze-downhole, kuquka uxinzelelo oluphezulu kunye nobushushu. Ngokukhetha le centralizer, abaqhubi banokuzithemba ekusebenzeni kwayo, besazi ukuba yenzelwe ukuqinisekisa ukusebenza kakuhle kwe-wellbore kunye nokuthembeka kwexesha elide.
