Ama-Centralizersziyithuluzi elibalulekile elisetshenziswa embonini kawoyela negesi ukuze kuqinisekiswe ukubekwa kahle kwemithombo yamanzi kanye nokusebenza kukasimende. Ezinhlotsheni ezahlukahlukene ezikhona,ama-centralizers aqinilezithandwa ngamandla azo kanye nokusebenza kahle, ikakhulukazi emithonjeni engadingi kakhulu. Ake singene sijule ezicini nasezinzuzweni zale mikhiqizo enamandla.
Ama-centralizers aqinilezenziwe ngensimbi eqinile, okwenza ziqine kakhulu futhi zimelane nokuguga. Lawa mandla abenza bakwazi ukumelana nezimo ezinzima ezivame ukuhlangana nazo emisebenzini yokumba. Ukwengeza, ukwakhiwa okuqinile kwalezi zinto ezimaphakathi kuqinisekisa ukusebenza okungaguquki ngisho nasezimweni eziyinselele.
Isici esiyinhloko seama-centralizers aqinilebacindezelwe nezindwani zabo. Lawa ma-vanes asebenza njengama-bearings ngesikhathi sokuzungezisa amapayipi, anciphisa izidingo ze-torque futhi akhulise ukusebenza kahle. Ukuklanywa okunembile kwama-blades kuvumela ukujikeleza kwamapayipi okubushelelezi, okungenamthungo, ukuthuthukisa ukusebenza kokumba jikelele.
Leziama-centralizerszitholakala ngamamodeli amabili: i-straight blade ne-helical blade. Imodeli ye-blade eqondile inikeza ukugxila okuhle kakhulu nokusekelwa kokuma kahle kwe-wellbore. Ifanele imithombo enezidingo ezilula, futhi ivame ukusetshenziswa emisebenzini yokumba enezidingo eziphansi.
Ukwengeza, umklamo we-helical blade usiza ukuvimbela umzila noma usimende ongaphelele. Ngokudala isiyaluyalu,ama-centralizersukukhuthaza ngisho nokusatshalaliswa kukasimende, kunciphisa ubungozi bezindawo ezibuthaka noma izikhala esigxotsheni sikasimende. Lokhu kuthuthukisa ukuhlukaniswa kwendawo futhi kuthuthukisa ubuqotho ngokuphelele bomthombo.
Ekuphetheni,ama-centralizers aqinilezingamathuluzi aqinile, ahlala isikhathi eside futhi asebenza kahle emithonjeni engadingi kakhulu. Ukwakhiwa kwayo kwensimbi eqinile kanye nokucindezelwa kanye nama-blades kuqinisekisa ukugxila okuphezulu kanye nokunciphisa i-torque ngesikhathi sokujikeleza kwamapayipi. Imodeli ye-straight blade yenza kube lula ukubekwa kahle kwe-wellbore, kuyilapho imodeli ye-helical blade idala isiyaluyalu, ithuthukisa ukusebenza kahle kokugudluzwa futhi isekela izindlela ezingcono kakhulu zikasimende. Ngokusebenzisaama-centralizers aqinile, ama-opharetha angathuthukisa ukusebenza kahle nobuqotho, aqinisekise ukuphumelela kokumba nokufaka usimende.
