Cov cement slurry yuav tsum nyob twj ywm ntev txaus kom ncav cuag lub hom phiaj qhov tob.
Yuav Ua Li Cas Cov Dej Loss Additive cuam tshuam rau lub sijhawm Thickening?
Nws tuaj yeem ua rau lub sijhawm thickening ntev dua los yog luv dua, nyob ntawm seb hom additive thiab zoo li cas.
1. Vim li cas thiaj ua tau aFluid Loss AdditiveHloov Lub Sijhawm Thickening?
Cov kua dej poob ntxiv tswj kev txav ntawm cov dej hauv cov slurry.
Thaum pom qhov txo qis, cov slurry khaws dej ntau dua thiab ua haujlwm tau ntev dua.
Qee cov additives kuj hnov mob nrog lwm cov tshuaj, uas yuav ua rau kom ceev lossis qeeb dej.
Qhov no txhais tau hais tias tib lub additive tuaj yeem ua txawv hauv cov qhov dej sib txawv.
Engineers yuav tsum sim cov slurry kom nkag siab tias cov additive yuav hloov lub sij hawm thickening li cas.
2. Dab tsi yog Kev Sib Raug Zoo Ntawm Kev Tswj Dej Tsis Txaus thiab Cov Dej Dej Thaum Cov Dej Loss Ntxiv Ntxiv?
Tus nqi dej ntawm cov cement tswj ceev npaum li cas cov slurry thickens.
Kev tswj kom tsis txhob muaj dej zoo dua txhais tau tias cov dej ntau nyob hauv cov slurry, yog li hydration ua qeeb.
Kev tswj tsis tau dej tsis zoo txhais tau hais tias lub cev qhuav dej sai dua, uas ua rau dej nrawm dua.
| Qib poob kua | Dej khaws cia | Dej nrawm | Qhov cuam tshuam rau lub sijhawm Thickening |
|---|---|---|---|
| Kev poob dej tsawg | Siab | qeeb | Thickening lub sij hawm nce |
| Cov kua dej nruab nrab | Nruab nrab | Ib txwm | Thickening lub sij hawm nyob twj ywm |
| High Fluid Poob | Tsawg | Ceev ceev | Thickening lub sij hawm yuav luv |
Nkag siab txog qhov txuas no pab cov engineers xaiv cov khoom ntxiv kom raug.
3. Yuav ua li cas sib txawv ntawm cov kua dej poob Additives cuam tshuam lub sij hawm Thickening?
Cov kua dej sib txawv ntawm cov khoom ntxiv coj txawv txawv hauv cov tshuab cement.
Qee lub sij hawm nce thickening, qee qhov qis dua, thiab qee qhov ua kom nws ruaj khov.
| Hom tshuaj ntxiv | Tej yam tshwm sim rau lub sij hawm Thickening | Yog vim li cas |
|---|---|---|
| Polymer{0}}raws li | Feem ntau nce | Muaj zog tuav dej |
| Starch-Raws li | Ntxiv me ntsis | Slows dej txav |
| Latex | Nruab nrab lossis nce | Tsim kom muaj kev tiv thaiv kev poob dej |
| HT Polymers | ruaj khov | Tsim los rau siab - qhov dej kub |
Vim tias qhov sib txawv no, engineers yuav tsum xaiv hom raug rau txhua qhov dej.
4. Qhov kub thiab txias hloov li cas aFluid Loss Additiventawm Thickening Time?
Qhov kub thiab txias muaj qhov cuam tshuam rau cov cement hydration.
Qhov kub thiab txias ua rau kom ceev ntawm hydration, ua rau lub sij hawm thickening luv.
Txawm hais tias tus additive tswj cov dej tsis zoo, lub sijhawm thickening tseem yuav poob rau hauv qhov dej kub.
Hauv cov dej txias, tib cov tshuaj ntxiv tuaj yeem ua rau lub sijhawm thickening ntau dua.
Qhov no yog vim li cas qhov kub thiab txias - cov kua dej tshwj xeeb yog xav tau rau HPHT qhov dej.
5. Cov Kev Xeem Li Cas Pab Cov Kws Ua Haujlwm Kom Paub Txog Cov Dej Loss Additive Effects ntawm Thickening Time?
Cov kev sim kuaj sim tso cai rau cov kws ua haujlwm saib seb cov tshuaj ntxiv coj li cas hauv cov xwm txheej zoo tiag tiag.
Cov kev ntsuam xyuas no xyuas cov twj tso kua mis, dej txav, thiab kev ruaj ntseg ntawm slurry.
| Cov khoom kuaj | Lub hom phiaj | Qhov Nws Qhia |
|---|---|---|
| Consistometer Test | Ntsuas lub sij hawm thickening | Pumpability qhov rais |
| API Fluid Loss Test | Ntsuas ntsuas | Muaj peev xwm tswj tsis tau dej |
| Rheology Test | Ntsuas tus cwj pwm ntws | Slurry stability |
Nrog rau cov kev sim no, engineers tuaj yeem kwv yees seb cov slurry yuav ua li cas hauv thaj teb.
6. Vim li cas Fluid Loss Additive Compatibility tseem ceeb rau lub sij hawm Thickening?
Cov kua dej poob ntxiv yuav tsum ua haujlwm zoo nrog cov tshuaj dispersants, retarders, accelerators, thiab lwm yam cement additives.
Yog tias cov additives tsis sib xws, lub sijhawm thickening yuav hloov mus rau hauv txoj kev engineers tsis xav txog.
Ib tug dispersant yuav txo viscosity ntau dhau, muab cov dej sib cais sai dua.
Ib qho retarder tuaj yeem ua rau qeeb dej ntau dua thaum sib xyaw nrog qee cov polymers.
Latex systems yuav coj txawv txawv thaum ua ke nrog ntsev los yog silica.
Qhov no yog vim li cas kev sim ua kom sib haum yog tsim nyog ua ntej ua haujlwm cement.

Los ntawm kev txheeb xyuas tus nqi dej, dej tuav, hom tshuaj ntxiv, qhov kub thiab txias, thiab cov txiaj ntsig kev kuaj sim, lawv tuaj yeem kwv yees seb lub sijhawm thickening yuav hloov li cas.
Nrog rau txoj kev tsim, cov slurry nyob twj ywm twj ywm ntev txaus thiab tsim cov cement sheath muaj zog.
