Sodium Carboxymethylcellulose siv hauv Petroleum Industries

Sodium Carboxymethylcellulose(CMC) yog cov dej-soluble polymer muab los ntawm cellulose uas yog siv nyob rau hauv ntau yam kev lag luam, nrog rau cov roj av. Hauv kev lag luam roj av, CMC yog siv los ua cov kua dej ntxiv, ua tiav cov kua dej ntxiv, thiab cov kua dej ntxiv ntxiv. Nws cov khoom tshwj xeeb ua rau nws yog ib qho tseem ceeb hauv ntau qhov kev tshawb nrhiav roj thiab roj thiab kev ua haujlwm ntau lawm. Kab lus no yuav tham txog ntau yam kev siv CMC hauv kev lag luam roj av.

1. Drilling Fluid Additive:

Drilling kua, tseem hu ua drilling av nkos, yog siv los lubricate thiab txias lub laum me ntsis, ncua kev xyaum txiav, thiab tswj lub siab nyob rau hauv lub qhov dej. CMC yog siv los ua cov kua dej ntxiv txhawm rau txhim kho cov viscosity, tswj kev pom, thiab shale inhibition zog ntawm cov av nkos. CMC kuj pab txo cov kua dej los ntawm kev tsim cov ncuav mog qab zib nyias, impermeable lim rau ntawm phab ntsa hauv qhov dej. Qhov no yuav pab tiv thaiv kom tsis txhob poob ntawm cov dej drilling rau hauv qhov tsim, uas tuaj yeem ua rau muaj kev puas tsuaj thiab txo cov khoom tsim tau zoo.

2. Ua kom tiav Fluid Additive:

Cov kua ua tiav yog siv los sau cov qhov dej tom qab drilling thiab ua ntej tsim khoom. Cov kua dej no yuav tsum tau sib haum nrog kev tsim thiab tsis ua rau lub reservoir puas. CMC yog siv los ua tiav cov kua dej ntxiv los tswj cov viscosity thiab cov kua dej poob ntawm cov kua. Nws pab tiv thaiv cov kua dej los ntawm kev nkag mus rau hauv kev tsim thiab ua rau kev puas tsuaj.

3. Fracturing Fluid Additive:

Hydraulic fracturing, tseem hu ua fracking, yog cov txheej txheem siv los txhawb kev tsim cov roj thiab roj los ntawm shale formations. Fracturing kua yog pumped mus rau hauv lub tsim nyob rau hauv siab siab, ua rau cov tsim kom puas thiab tso cov roj thiab roj. CMC yog siv los ua cov kua dej ntxiv los txhim kho cov viscosity thiab cov kua dej poob ntawm cov kua. Nws kuj tseem pab kom tshem tawm cov khoom tawm, uas yog siv los tuav qhib cov pob txha hauv qhov tsim.

4. Fluid Loss Control:

Kev poob dej yog qhov kev txhawj xeeb loj hauv kev ua haujlwm drilling thiab ua tiav. CMC yog siv los ua tus neeg saib xyuas kev poob dej los tiv thaiv qhov poob ntawm qhov drilling thiab ua tiav cov kua hauv qhov tsim. Nws tsim lub ncuav mog qab zib nyias, impermeable lim rau ntawm phab ntsa hauv lub qhov dej, uas yuav pab tiv thaiv kom tsis txhob muaj dej poob thiab tsim kev puas tsuaj.

5. Shale Inhibition:

Shale yog hom pob zeb uas feem ntau ntsib hauv kev tshawb nrhiav roj thiab roj thiab kev tsim khoom. Shale muaj cov ntsiab lus av nplaum siab, uas tuaj yeem ua rau nws o thiab tawg thaum raug dej raws li cov dej drilling. CMC yog siv los ua tus neeg sawv cev shale inhibition los tiv thaiv shale los ntawm o thiab tawg. Nws tsim cov txheej txheem tiv thaiv ntawm cov khoom shale, uas yuav pab kom ruaj khov thiab tiv thaiv lawv los ntawm kev cuam tshuam nrog cov kua dej drilling.

6. Rheology Modifier:

Rheology yog kev kawm txog cov dej ntws. CMC yog siv los ua tus hloov kho rheology hauv kev drilling, ua tiav, thiab cov kua dej tawg. Nws txhim kho cov viscosity thiab shear-thinning zog ntawm cov kua, uas yuav pab kom muaj kev ruaj ntseg ntawm cov kua thiab tiv thaiv nws los ntawm kev daws teeb meem.

7. Emulsifier:

Ib qho emulsion yog qhov sib xyaw ntawm ob cov kua dej tsis sib xws, xws li roj thiab dej. CMC yog siv los ua ib qho emulsifier hauv drilling thiab ua tiav cov kua dej kom ruaj khov rau emulsion thiab tiv thaiv cov roj thiab dej los ntawm kev sib cais. Qhov no pab txhim kho kev ua haujlwm ntawm cov kua dej thiab tiv thaiv kev tsim kev puas tsuaj.

Hauv kev xaus, CMC yog ntau yam polymer uas tau siv dav hauv kev lag luam roj av. Nws cov khoom tshwj xeeb ua rau nws yog ib qho tseem ceeb hauv ntau qhov kev tshawb nrhiav roj thiab roj thiab kev ua haujlwm ntau lawm. Nws yog siv raws li ib tug drilling kua additive, ua tiav kua additive, thiab fracturing kua additive. Nws kuj tseem siv rau kev tswj tsis tau dej, shale inhibition, rheology hloov kho, thiab emulsification.
