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 yonke kuyenza ibe ukukhetha okuthembekile futhi okusebenzayo kumaWell angasogwini aqondile, avundlile futhi athambekele. Ikhono layo lokumelana nezindawo eziqinile ze-casing liqinisekisa ukusebenza ngempumelelo kukasimende futhi lithuthukisa ubuqotho nempilo yesevisi.
