Cement txhawb thiab tiv thaiv zoo casings thiab pab ua kom tiav zonal cais.Qhov tseem ceeb rau kev nyab xeeb, ib puag ncig zoo, thiab cov txiaj ntsig zoo, kev sib cais zonal yog tsim thiab tswj xyuas hauv qhov dej los ntawm cov txheej txheem cementing.Kev sib cais ntawm Zonal tiv thaiv cov kua dej xws li dej lossis roj hauv ib cheeb tsam los ntawm kev sib xyaw nrog cov roj hauv lwm cheeb tsam.Qhov no yog ua tiav los ntawm kev tsim cov hydraulic barrier ntawm lub casing, cement thiab tsim.Cement additives yog cov khoom siv ntxiv rau cov cement rau kev ua kom zoo ntawm cov khoom cement thiab cov txheej txheem sib tsoo cov cement.Cement additives tau muab faib ua cov khoom sib txawv xws li kev sib tsoo, cov khoom siv dag zog thiab kev ua haujlwm zoo.Muaj ob hom kev ua ub no hauv cementing, uas yog, thawj thiab theem nrab cementing.Lub hauv paus cementing kho cov hlau casing mus rau ib puag ncig tsim.Secondary cementing yog siv los sau formations, sealing, los yog dej kaw.Qhov kev ua tau zoo tuaj yeem sib txawv los ntawm qhov sib ntxiv ntawm cov additives hais txog ntau yam.Nyob ntawm daim ntawv thov ntawm cov cement, ntau yam additives tuaj yeem muab tso ua ke.Cov no muaj xws li accelerators, retarders, dispersants, extenders, weighting agents, gels, foamers, thiab kua poob additives.Foring Chemcials muaj ntau yam khoom zoo tshwj xeeb tshuaj additives rau oilfield daim ntaub ntawv thiab kuj muab tailor-made tsim los pab txhawb thiab txhim khu cov txheej txheem cementing.Cement dispersants txhim kho cov slurry rheology xws li kev siv ntev ntev tau txhim kho zoo heev thiab tib lub sijhawm cov dej txo cov cement slurries tuaj yeem ua tau.Cov kua dej poob ntxiv, uas ruaj khov tiv thaiv qhov kub thiab txias cov ntsiab lus ntsev, ua kom muaj kev txhim khu kev qha cementing txoj haujlwm nyob rau hauv cov xwm txheej nyuaj.Retarders tuaj yeem sib koom ua ke nrog peb cov neeg ua haujlwm tau zoo heev uas tso cai rau lub sijhawm tseem ceeb hauv kev ua haujlwm cementing nyob rau hauv qhov kub thiab txias.Cov tshuaj tiv thaiv kev tsiv teb tsaws chaw tiv thaiv cov pa roj los ntawm kev xa mus los ntawm cov cement hardening thiab xyuas kom muaj kev ruaj ntseg cementing txoj haujlwm, thaum peb cov defoamers muaj cov khoom ua npuas ncauj zoo heev.
