Centralizersyog cov cuab yeej tseem ceeb siv hauv kev lag luam roj thiab roj kom ntseeg tau tias qhov chaw zoo thiab kev ua haujlwm cementing.Ntawm ntau hom muaj,nruj centralizersyog nrov rau lawv lub zog thiab kev ua haujlwm zoo, tshwj xeeb tshaj yog rau cov qhov dej tsis tshua xav tau.Cia peb nkag siab tob rau hauv cov yam ntxwv thiab cov txiaj ntsig ntawm cov khoom muaj zog no.
Rigid centralizersyog ua los ntawm cov khoom hlau, ua rau lawv tsis tshua muaj zog thiab tiv taus hnav thiab tsim kua muag.Lub zog no tso cai rau lawv tiv taus cov xwm txheej hnyav uas feem ntau ntsib hauv kev ua haujlwm drilling.Tsis tas li ntawd, kev tsim kho zoo ntawm cov centralizers no ua kom muaj kev ua tau zoo ib yam txawm tias nyob hauv ib puag ncig nyuaj.
Ib qho tseem ceeb feature ntawmnruj centralizersyog lawv pressed thiab hniav.Cov vanes no ua zoo li cov kabmob thaum lub sijhawm sib hloov cov yeeb nkab, txo cov kev xav tau ntawm lub zog thiab ua kom muaj kev ua haujlwm zoo tshaj plaws.Cov qauv tsim ntawm cov hniav tso cai rau kom du, seamless yeeb nkab tig, kev txhim kho tag nrho cov drilling kev ua tau zoo.
Cov nocentralizersmuaj nyob rau hauv ob lub qauv: ncaj hniav thiab helical hniav.Cov qauv hniav ncaj ncaj muab kev ua kom pom tseeb thiab kev txhawb nqa rau qhov chaw zoo.Nws yog qhov tsim nyog rau cov qhov dej nrog cov kev xav tau yooj yim, thiab feem ntau siv hauv kev ua haujlwm drilling nrog cov kev xav tau tsawg.
Tsis tas li ntawd, lub helical hniav tsim pab tiv thaiv channeling los yog tsis tiav cementing.Los ntawm inducing turbulence,centralizerstxhawb nqa txawm tias kev faib cov cement, txo qhov kev pheej hmoo ntawm cov chaw tsis muaj zog lossis cov voids hauv cov cement sheath.Qhov no txhim kho zonal cais thiab txhim kho tag nrho cov kev ncaj ncees ntawm lub qhov dej.
Hauv kev xaus,nruj centralizersyog cov cuab yeej muaj zog, ruaj khov thiab muaj txiaj ntsig zoo rau cov dej tsis xav tau.Nws cov khoom steel siv thiab nias thiab cov hniav kom zoo tshaj plaws concentration thiab torque txo thaum cov yeeb nkab tig.Cov qauv hniav ncaj ncaj pab txhawb qhov chaw zoo, thaum lub helical hniav qauv induces turbulence, txhim kho kev khiav hauj lwm efficiency thiab txhawb cov cementing zoo tshaj plaws.Los ntawm kev sivnruj centralizers, cov neeg ua haujlwm tuaj yeem txhim kho kev ua tau zoo thiab kev ncaj ncees, ua kom muaj kev vam meej ntawm kev ua haujlwm drilling thiab cementing.
