Ucezu olulodwaBow spring casing centralizerisanda kubuya, okuyenza ibe yinketho yokuqala emithonjeni emile, evundlile noma echezukile esogwini. Lesi siguqulii-centralizeryakhelwe ukuhlinzeka ngokusebenza okungenakuqhathaniswa endaweni yokusebenza ye-casing enokhahlo.
Esinye sezici ezivelele zebow spring centralizersukuqina kwabo. Iyakwazi ukumelana nezimo ezinzima kakhulu ezihlangabezane nazo ngesikhathi sokufakwa kwe-bushing. Ukwakhiwa kwayo okuhlala isikhathi eside kuqinisekisa ukuthi ingakwazi ukumelana nezingcindezi ezinkulu kanye nomklamo oqinile womthombo, okuyenza ibe ilungele izinhlelo zokusebenza zasogwini eziyinselele.
Naphezu kobude be-Bow spring centralizermfushane, futhi ithola amandla amakhulu okubuyisela. Igcina izinga eliphezulu lamandla, iqinisekisa ukugcinwa kwebanga okusebenzayo ngenkathi i-casing. Leli khono libalulekile ekuqinisekiseni ukusebenza kahle kukasimende kanye nobuqotho bemithombo.
Ngokungafani ne-centralizer yendabuko, equkethe izingxenye eziningi, i-OBU iyiyunithi eqinile. Lo mklamo ongenamthungo uqeda ingozi yokwehluleka okubangelwa ukuhlukaniswa kwengxenye futhi uqinisekisa ukwethembeka kwe-wellbore.
Ukuze kuthuthukiswe ukusebenza kwe-OBU centralizer, kusetshenziswe inqubo yokwelapha ukushisa okuphathelene. Le nqubo inika i-centralizer ibhalansi ephelele yokuguquguquka komnsalo namandla. Umnsalo ungamelana nokugoba ngesikhathi sokufakwa kwe-casing ngenkathi ugcina umumo wawo wangempela nomsebenzi. Lokhu kuqinisekisa ukuthi i-centralizer inikeza imvume engaguquki kuyo yonke imisebenzi ye-casing.
I-OBU ingxenye eyodwaBow spring casing centralizeriwushintsho ngempela embonini kawoyela negesi. Ukuqina kwayo, ukuqina kwayo okuphezulu kanye nokwakhiwa kwayo konke kuyenza ibe ukukhetha okuthembekile futhi okusebenzayo kuma-Well angasogwini aqondile, avundlile futhi athambekele. Ikhono layo lokumelana nezindawo eziqinile ze-casing liqinisekisa ukusebenza ngempumelelo kukasimende futhi lithuthukisa ubuqotho nempilo yesevisi.
