Lub centralizer, tseem hu ua tus corrector, yog siv los xyuas kom meej tias cov hlua casing nyob rau hauv nruab nrab ntawm lub qhov dej nyob rau hauv cov roj thiab roj drilling.
Lub hauv paus tseem ceeb heev rau cov roj drilling, thiab qhov sib txawv me ntsis ntawm qhov loj me, qauv thiab cov khoom siv yuav muaj kev cuam tshuam rau kev nce qib ntawm drilling.
Muaj ntau hom centralizers, xws li: elastic centralizers, rigid centralizers, semi-rigid centralizers, roller centralizers, tubing centralizers, sucker rod centralizers, thiab lwm yam.
Cov qauv tsim thiab cov qauv ntawm cov centralizer tsis nyuaj, thiab ntau lub tuam txhab me me tuaj yeem ua qee yam ntawm lawv tus kheej tom qab tau txais cov duab kos.
Txawm li cas los xij, kev tsim cov centralizers tsis yog tsuas yog welded nrog cov hlau, thiab kev siv tom ntej yuav cuam tshuam txog cov teeb meem kev nyab xeeb.
Thaum xaiv, koj yuav tsum xav txog cov khoom siv, qauv, txheej txheem zoo, daim ntawv pov thawj kev nyab xeeb khoom thiab lwm yam raws li qhov tsim nyog, thiab nco ntsoov tias pheej yig.
