Uma kufikaama-centralizers, amandla, ukuguquguquka nokuthembeka kubaluleke kakhulu. Ezinhlelweni eziyinselelo ikakhulukazi lapho ucezu olulodwa lomkhiqizo ludingeka khona,ama-hinge centralizerssebeyisinqumo sokuqala. Njengoba iklanyelwe ngokukhethekile ukuhlangabezana nezidingo zokuqina okuphezulu nezimo eziyinselele, lezi zinto ezimaphakathi zinikeza ukuguquguquka okukhulu nokuthembeka ekusebenzeni kahle kwe-wellbore.
Olunye uhlobo lokukhulumai-centralizerokugqamayo emakethe wukukhulumaBow spring centralizer. Eyaziwa ngokwakhiwa kwayo kwekhwalithi ephezulu, le centralizer inikeza ukusebenza okungenakuqhathaniswa ezinhlelweni ezihlukahlukene, kuhlanganise nolwandle, ulwandle, amanzi ajulile kanye nemithombo echezuke kakhulu.
Iyachazabow spring centralizerszenzelwe ukunikeza ukuguquguquka okuphakeme ngaphandle kokuphazamisa ukuqina. Ukwakhiwa kwayo okunamahenjisi okwenza ilungele ama-wellbores angaqondile ngokuphelele. Lokhu kuguquguquka kuqinisekisa i-casing ekujuleni okufunayo, kukhuthaza u-cementing ophumelelayo futhi kunciphisa ingozi yokulimala kokubunjwa.
Ngaphezu kokuvumelana nezimo,kuncike bow spring centralizersiqinisekisa lokhoyayoingadlula kalula ezithiyo nasemigodini emincane ngesikhathi sokufakwa. Amandla okuqalisa ancishisiwe asiza futhi ukusebenza kahle kwe-casing futhi anciphise ithuba lokunamathela kwe-casing njengoba yehliswa imbobo engezansi.
Esinye isici esibalulekile sokukhulumabow spring centralizersingamandla abo aphezulu okubuyisela. I-centralizer iyakwazi ukusebenzisa amandla aqinile ekucindezelweni, iqinisekise ukuvunyelwa okuphezulu, ithuthukise ukugudluzwa kukasimende kanye nokukhuthaza ubuqotho bobuqotho. Amandla okubuyisela athuthukisiwe aqinisekisa futhi ukuthi i-casing igxile ngokuphumelelayo emgodini womthombo, ukunciphisa ukunyakaza koketshezi olunyakazayo, ngaleyo ndlela kuncishiswe ubungozi bomzila kanye nokuhlukaniswa kabi kwendawo.
I-Hingedbow spring centralizerszenzelwe ukuthi ziphumelele ezinhlelweni eziyinselele lapho amandla nokuthembeka kubalulekile. Ukwakhiwa kwayo okuqinile kanye nezinto ezisezingeni eliphezulu kuyivumela ukuba imelane nezimo ezinzima zemigodi, kuhlanganise nokucindezela okuphezulu kanye nezinga lokushisa. Ngokukhetha lesi sithako esimaphakathi, opharetha bangaba nokuzethemba ekusebenzeni kwaso, bazi ukuthi siklanyelwe ukuqinisekisa ukusebenza kahle kwe-wellbore kanye nobuqotho besikhathi eside bomthombo.
