Sei tichifanira kushandisa casing centralizer?

Kushandisa casing centralizer inzira yakakosha yekuvandudza kunaka kwecement.

Chinangwa chekusimbisa chine zvinhu zviviri: chekutanga, kuvhara zvikamu zvematsime zvinogona kudonha, kubuda kwemvura, kana zvimwe zvinhu zvakaoma zvine casing, kuitira kuti pave nevimbiso yekuti kuchera kwakachengeteka uye kwakapfava kucharamba kuripo. Chechipiri ndechekuvhara zvinobudirira magadzirirwo akasiyana emafuta negasi, kuitira kudzivirira mafuta negasi kuti asabude pasi kana kubuda pakati pemagadzirirwo, uye kupa nzira yekugadzira mafuta negasi.

Zvichienderana nechinangwa chekusimbisa, nzira dzekuongorora kunaka kwekusimbisa dzinogona kuwanikwa. Zvinonzi kunaka kwekusimbisa zvinoreva kuti chivharo chiri pakati pechibhorani uye mhete yesimende yakakomberedza chivharo inoparadzanisa chivharo kubva kumadziro etsime uye kuumbwa kubva pakuumbwa. Zvisinei, chibhorani chaicho chakaboorwa hachina kumira zvakanaka, uye tsime rakatsveyama richagadzirwa kusvika padanho rakasiyana. Nekuda kwekuvapo kwekunamira kwetsime, chivharo hachizove pakati pechibhorani, zvichikonzera chiitiko chehurefu hwakasiyana uye madhigirii akasiyana ekunamatira kumadziro etsime. Kuumbwa kwebhokisi uye mukaha wemadziro etsime pakati pehukuru hwakasiyana, kana simende inopinda nemukaha yakakura, dhaka rekutanga riri nyore kutsiva dhaka; pane zvinopesana, mukaha mudiki, nekuda kwekudzivirira kwemvura yakakura, simende inodzivirira zvakaoma kutsiva dhaka rekutanga, kuumbwa kwechiitiko chinozivikanwa che slurry slurry trenching. Mushure mekuumbwa kwechiitiko che trenching, haigone kuvhara mafuta negasi, mafuta negasi zvichayerera nepakati pezvikamu zvisina simende ring.

Kushandisa casing centralizers kuita kuti casing ive pakati zvakanyanya sezvinobvira panguva yekuisa simende. Kune matsime anotungamira kana matsime ane nzvimbo yakakura, zvinonyanya kukosha kushandisa casing centralizer. Pamusoro pekudzivirira zvinobudirira simende kuti isapere mugomba, kushandisa casing corrector kunoderedzawo njodzi yekuti casing ibatwe nekumanikidzwa kwakasiyana. Nekuti casing iri pakati, casing haizove pedyo nemadziro etsime, uye kunyangwe muchikamu chetsime chine mukana wakanaka, casing haizonamirwi nyore nyore nekeke rematope rinoumbwa nekumanikidzwa kwakasiyana, izvo zvinozotungamira mukuboorwa kwakanamirwa. Casing centralizer inogonawo kuderedza mwero wekukombama kwecasing mutsime (kunyanya muchikamu chikuru cheborehole), izvo zvinoderedza kupera kwezvishandiso zvekuboorera kana zvimwe zvishandiso zvepaburi pacasing panguva yekuboorera mushure mekunge casing yadzikiswa, uye inobatsira pakudzivirira casing. Nekuda kwechikamu chinoisa simbi pakati pechivharo nemudziyo unoisa simbi pakati pechivharo, nzvimbo yekubata pakati pechivharo nemadziro etsime inodzikira, izvo zvinoderedza kukweshana pakati pechivharo nemadziro etsime, uye zvinobatsira kudzikisa chivharo mutsime, uye zvinobatsira kufamba kwechivharo pakusimira chivharo.

Mukupfupisa, kushandisa casing centralizer inzira iri nyore, iri nyore uye inokosha yekuvandudza kunaka kwecement.
