Humic acid hom kua dej poob additive yog hom polymer roj zoo cement kua dej poob additive uas tau txais kev muaj koob meej nyob rau hauv xyoo tas los no.Raws li ib qho ntawm cov khoom lag luam tshiab ntawm Oilbayer, lub tuam txhab tshwj xeeb hauv R & D thiab kev tsim cov tshuaj oilfield, cov kua dej tsis zoo no tau tsim los pab cov neeg ua haujlwm roj thiab roj hauv kev tshawb nrhiav kom muaj txiaj ntsig ntau tshaj plaws thiab ua haujlwm tau zoo.
Hom tshuaj ntxiv no feem ntau yog tsim los ntawm kev sib xyaw ntawm AMPS / NN / humic acid nrog kub zoo thiab ntsev tsis kam.Cov humic acid ua raws li lub ntsiab monomer, thaum lwm cov ntsev-resistant monomers ua ke los txhim kho nws cov hauj lwm zoo.Qhov tshwm sim yog ib qho kev siv tau zoo heev uas tuaj yeem pab txo cov dej poob thaum lub sij hawm zoo cementing, yog li optimizing lub qhov dej zoo thiab txhim kho tag nrho cov nyiaj rov qab los ntawm kev nqis peev.
Kev poob dej yog ib qho teeb meem tshwm sim hauv kev lag luam roj thiab roj, tshwj xeeb tshaj yog thaum ua haujlwm cementing.Nws tshwm sim thaum cov kua siv los ua cement lub qhov dej nkag mus rau hauv cov pob zeb tsim, tawm hauv cov voids uas txo lub zog ntawm cov cement bond.Qhov no tuaj yeem ua rau muaj ntau yam teeb meem, xws li txo cov khoom tsim tau, nce nqi txij nkawm, thiab txawm tias muaj teeb meem kev ncaj ncees.
Humic acid hom kua dej poob additive pab kom txo tau cov teeb meem no los ntawm kev tsim ib txheej tiv thaiv nyob ib ncig ntawm lub qhov dej.Cov txheej no ua raws li kev thaiv, tiv thaiv cov kua cement los ntawm kev nkag mus rau hauv kev tsim thiab txo cov kua dej uas ploj thaum lub sijhawm ua haujlwm cementing.Qhov no yog ua tiav los ntawm kev sib xyaw ntawm cov polymer cov khoom tshwj xeeb, uas pab ua kom cov viscosity ntawm cov kua cement thiab tiv thaiv nws los ntawm ntws mus rau hauv qhov dej.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv humic acid hom kua dej poob additives yog lawv qhov kub thiab txias tsis kam.Qhov no txhais tau hais tias lawv tuaj yeem siv tau rau ntau qhov chaw ib puag ncig, suav nrog cov txheej txheem kub thiab cov dej ntsev ntau.Qhov no versatility ua rau lawv yog ib qho kev xaiv zoo tshaj plaws rau cov neeg ua haujlwm roj thiab roj nrhiav kom ua kom muaj txiaj ntsig thiab tsim tau zoo ntawm lawv cov haujlwm drilling.
Hauv kev xaus, humic acid hom kua dej poob ntxiv yog ib qho kev daws teeb meem tshiab rau cov teeb meem poob dej uas tau ntsib los ntawm kev lag luam roj thiab roj.Tsim los ntawm Oilbayer, cov khoom no muab cov txiaj ntsig tshwj xeeb ntawm AMPS / NN / humic acid nrog rau lwm cov ntsev-resistant monomers los tsim cov khoom siv tau zoo heev uas tuaj yeem siv rau ntau yam kev siv.Yog tias koj txaus siab rau kev txhim kho cov khoom tsim tau thiab kev ua haujlwm ntawm koj qhov kev ua haujlwm drilling, xav txog kev sib xyaw humic acid hom kua dej poob additive rau hauv koj cov kev ua haujlwm cementing.
MEDIUM THIAB QHOV CHAW UA HAUJ LWM POLYMER FLUID LOSS REDUCER
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.
