Sodium Carboxymethylcellulose siv hauv Petroleum Industries

Sodium carboxymethylcellulose (CMC) muaj ntau daim ntawv thov tseem ceeb hauv kev lag luam roj av, tshwj xeeb tshaj yog nyob rau hauv cov dej drilling thiab txhim kho cov txheej txheem roj rov qab. Nov yog qee qhov kev siv tseem ceeb ntawm CMC hauv kev siv roj av:

1. Drilling kua:
   • Viscosity Control: CMC yog ntxiv rau cov dej drilling los tswj cov viscosity thiab txhim kho rheological zog. Nws pab tswj tau qhov xav tau viscosity ntawm cov dej drilling, uas yog qhov tseem ceeb rau kev nqa cov laum txiav mus rau saum npoo thiab tiv thaiv kom tsis txhob tawg.
   • Fluid Loss Control: CMC ua raws li tus neeg saib xyuas cov dej poob los ntawm kev tsim cov ncuav mog qab zib nyias, impermeable lim rau ntawm phab ntsa hauv qhov dej. Qhov no pab txo cov kua dej poob rau hauv kev tsim, tswj kev ruaj ntseg zoo, thiab tiv thaiv kev tsim kev puas tsuaj.
   • Shale Inhibition: CMC inhibits shale o thiab dispersion, uas yuav pab kom stabilize shale formations thiab tiv thaiv wellbore instability. Qhov no yog tshwj xeeb tshaj yog tseem ceeb nyob rau hauv formations nrog av nplaum ntsiab lus.
   • Kev ncua thiab kev thauj mus los: CMC txhim kho qhov kev ncua thiab kev thauj mus los ntawm cov laum txiav hauv cov dej drilling, tiv thaiv kev daws teeb meem thiab ua kom muaj txiaj ntsig tshem tawm ntawm lub qhov dej. Qhov no pab tswj kev huv huv thiab tiv thaiv cov khoom puas.
   • Kub thiab Salinity Stability: CMC nthuav tawm kev ruaj ntseg zoo tshaj qhov ntau ntawm qhov kub thiab txias thiab qib salinity ntsib hauv kev ua haujlwm drilling, ua rau nws tsim nyog siv rau ntau qhov chaw drilling.
2. Txhim Kho Roj Rov Qab (EOR):
   • Dej Flooding: CMC yog siv rau hauv dej nyab dej ua haujlwm ua tus neeg saib xyuas kev txav mus los txhawm rau txhim kho cheb cov dej txhaj tshuaj thiab txhim kho cov roj rov qab los ntawm cov dej ntws. Nws pab txo cov dej channeling thiab ntiv tes, kom ntseeg tau tias muaj kev sib hloov ntawm cov roj ntau dua.
   • Polymer Flooding: Nyob rau hauv cov txheej txheem dej nyab polymer, CMC feem ntau yog siv los ua tus neeg sawv cev thickening ua ke nrog lwm cov polymers los ua kom cov viscosity ntawm cov dej txhaj. Qhov no txhim kho lub cheb efficiency thiab tshem tawm efficiency, ua rau cov roj rov qab ntau dua.
   • Kev Hloov Kho Profile: CMC tuaj yeem siv rau kev kho qhov profile los txhim kho cov dej ntws ntws hauv cov reservoirs. Nws pab tswj cov dej txav mus los thiab xa rov qab ntws mus rau thaj chaw tsawg-swept, ua kom cov roj ntau ntau los ntawm cov chaw ua haujlwm tsis zoo.
3. Kev ua haujlwm thiab ua tiav cov kua dej:
   • CMC tau ntxiv rau kev ua haujlwm thiab ua tiav cov kua dej los muab kev tswj viscosity, tswj tsis tau dej, thiab cov khoom raug ncua. Nws pab tswj kom muaj kev ruaj ntseg zoo thiab huv si thaum ua haujlwm ua haujlwm thiab ua tiav cov haujlwm.

sodium carboxymethylcellulose plays lub luag haujlwm tseem ceeb hauv ntau yam ntawm kev tshawb nrhiav roj av, drilling, ntau lawm, thiab txhim kho cov txheej txheem roj rov qab. Nws versatility, ua tau zoo, thiab compatibility nrog rau lwm yam additives ua rau nws ib tug tseem ceeb feem ntawm drilling kua thiab EOR kev kho mob, pab txhawb rau kev ua tau zoo thiab nqi-zoo roj av.
