qhia:
Polymer roj zoo cementing tshuab tau dav siv nyob rau hauv kev tshawb nrhiav thiab kev loj hlob ntawm cov roj thiab roj.Ib qho ntawm cov khoom tseem ceeb hauv cov tshuab polymer cementing yog cov tshuaj tiv thaiv dej tsis zoo, uas tuaj yeem txo cov dej poob thaum lub sij hawm cementing txheej txheem.Kev siv cov tshuab polymer cement muaj ntau yam zoo xws li lub zog siab, tsis muaj permeability, thiab kev ua tau zoo sealing zoo.Txawm li cas los xij, qhov teeb meem tshwm sim hauv cov txheej txheem no yog dej poob, uas yog, cov cement slurry seeps rau hauv kev tsim, ua rau nws nyuaj rau rub tawm lub raj thaum cov roj rov qab.Yog li ntawd, txoj kev loj hlob ntawm nruab nrab thiab qis kub kua poob reducer tau dhau los ua qhov tseem ceeb ntawm oilfield cementing technology kev vam meej.
Polymer roj zoo cement fluid poob reducer:
Cov kua dej poob additive yog ib qho khoom siv tseem ceeb rau kev npaj cov cement slurry.Nws yog cov hmoov uas yooj yim soluble hauv dej thiab muaj cov khoom sib xyaw zoo.Thaum lub sij hawm tsim tawm, cov kua dej tswj cov neeg ua haujlwm tau sib xyaw nrog lwm cov khoom siv los tsim cov cement slurry homogeneous thiab ruaj khov.Tus neeg saib xyuas kev poob dej ua lub luag haujlwm tseem ceeb hauv kev txo cov kua dej poob thaum lub sij hawm cementing txheej txheem.Nws txo cov kev tsiv teb tsaws ntawm cov dej hauv cov av nkos mus rau ib puag ncig formations thiab txhim kho cov khoom siv ntawm cov cement.
Kev poob dej ≤ 50:
Thaum siv cov kua dej txo cov neeg ua haujlwm, nws yog ib qho tseem ceeb uas yuav tsum tswj cov kua dej poob hauv qee qhov ntau, feem ntau tsawg dua lossis sib npaug li 50ml / 30min.Yog tias cov dej poob siab dhau lawm, cov cement slurry yuav nkag mus rau hauv qhov tsim, ua rau borehole channeling, av nkos, thiab cementing tsis ua haujlwm.Ntawm qhov tod tes, yog tias cov dej poob qis dhau lawm, lub sij hawm cementing yuav nce ntxiv, thiab yuav tsum muaj tus neeg sawv cev tiv thaiv dej ntxiv, uas ua rau cov txheej txheem nce nqi.
Nruab nrab thiab qis kub kua poob reducer:
Thaum lub sij hawm cementing txheej txheem hauv oilfields, cov dej poob tus nqi cuam tshuam los ntawm ntau yam xws li kev tsim kub, siab, thiab permeability.Tshwj xeeb, qhov kub ntawm cov kua cementing muaj qhov cuam tshuam loj rau cov kua dej poob.Cov kua dej poob zoo li yuav nce siab ntawm qhov kub thiab txias.Yog li ntawd, nyob rau hauv cov txheej txheem cementing, nws yog ib qho tsim nyog yuav tsum tau siv cov kua nruab nrab thiab qis qis qis ntxiv uas tuaj yeem txo cov kua dej poob ntawm qhov kub thiab txias.
Hauv cov ntsiab lus:
Nyob rau hauv luv luv, polymer roj zoo cementing tshuab tau dhau los ua ib qho tseem ceeb thev naus laus zis rau kev tshawb nrhiav thiab kev loj hlob ntawm cov roj thiab roj.Ib qho tseem ceeb ntawm cov thev naus laus zis no yog tus neeg sawv cev los tiv thaiv dej, uas ua lub luag haujlwm tseem ceeb hauv kev txo cov dej poob thaum lub sij hawm cementing txheej txheem.Kev tswj cov dej poob thaum lub sij hawm npaj av nkos kuj ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev vam meej ntawm cov txheej txheem cementing.Txoj kev loj hlob ntawm nruab nrab thiab qis kub kua dej poob reducers yog qhov tseem ceeb rau kev txhim kho cementing efficiency, txo cov nqi thiab txhim kho kev ncaj ncees ntawm cov roj thiab cov qhov dej.
