Pakuchera mafuta negasi matsime, kumhanyisa casing kusvika pazasi pegomba uye kuwana yakanaka simende mhando kwakakosha. Casing ndiyo tubing inodzika mutsime kudzivirira tsime kubva pakuputsika uye kuparadzanisa nzvimbo inogadzirwa kubva kune mamwe maumbirwo. Casing inofanirwa kuve yakanyatso kurongeka uye yakachengetedzwa munzvimbo kuti ive nechokwadi chekuita zvakanaka uye kuchengetedzeka. Apa ndipocentralizerskupinda kutamba.
A centralizersmudziyo unobatsira kuti casing irambe iripo uye kuti irambe iri pakati pechibhorani panguva yekuisa simende.Centralizerszvinhu zvakakosha zvemidziyo yekupedzisa nekuti vanovimbisa kuti simende inozadza zvakaenzana pakati pekasi nemadziro etsime, ichigadzira chisungo chakasimba uye kudzivirira kutama kwemvura.
Centralizersvane zvakasiyana-siyana zvemagadzirirwo uye masitayera, kubva pabow spring uyerigid centralizerskushanduro itsva, dzepamusoro-soro dzakadai sematenderedzwa uye asingatenderere epakati. Midziyo iyi inosarudzwa zvinoenderana nemamiriro etsime uye simende zvinodiwa. Semuyenzaniso, akaomesesa ekutsigira centralizer anokodzera matsime akatwasuka uye matsime akarerekera zvakanyanya ane kushoma kubhenda, ukuwo.Bow spring centralizersakakodzera matsime akarerekera uye madiki-angle matsime ane zvakawanda zvinodiwa.
Kana iyo casing isinganyatso kuomeswa, simenti haizogovaniswa zvakaenzana, izvo zvinogona kutungamirira kune localized simende sheaths kana channeling effects. Izvi zvakare zvinogona kukanganisa kuita kwetsime uye, zvinotonyanya kukosha, kuchengetedza. Chikamu chesimende sheath chinogona kukonzera simende kutadza uye kubvumira kufamba kwemvura, kukanganisa kutendeseka uye kugadzira njodzi dzinogona kuitika kwezvakatipoteredza.
Kuti udzivise matambudziko akadai, zvakakosha kuti usarudze chaiyo centralizer uye uve nechokwadi chekuisa kwakaringana. Vamwecentralizers, kunyanya mhando itsva dzinotenderera uye dzisingatenderere, dzinopa hukuru hwekuisa huchokwadi uye mazinga epamusoro ekuita kupfuura echinyakare centralizer.
Maitiro ekuisa akakodzera anofanirwa kuteverwa kuti uwane yakanyanya kubatana pakati pecasing uye tsime madziro. Nekutevera nhungamiro idzi, thecentralizersinogona kusimbisa tsime uye pakati pecasing zvakakwana, zvichikonzera yemhando yepamusoro, inobereka uye yakachengeteka mutsime.
