Kev siv ntawmCmc nyob rau hauv oilfieldKev ua hauj lwm

Carboxymethyl cellulose (CMC) tau siv dav hauv kev lag luam roj rau ntau yam kev siv vim nws cov khoom ntiag tug thiab kev ua haujlwm. Nws ua haujlwm ua ib qho kev sib txawv ntxiv hauv cov kua dej drilling, cov kua dej ua tiav, thiab cementing slurries, ntawm lwm cov kev siv. Nov yog qee qhov kev siv ntawm CMC hauv Kev Lag Luam Kev Lag Luam Roj:

1. Drilling kua:

• Viscosifier: CMC yog siv los ua tus neeg sawv cev viscosifying hauv dej-raws li cov dej lim kom nce vencosity thiab txhim kho cov kua roj nqa muaj peev xwm. Nws pab tswj kom muaj kev ruaj khov, thiab kev tswj cov kua dej los thaum lub sijhawm ua haujlwm drilling.
• Kev tswj cov kua dej: CMC ua raws li kev tswj cov kua dej los ntawm kev tsim cov roj lim nyias, tiv thaiv cov kua dej zoo heev rau hauv kev tsim.
• Shale Inhibition: CMC pab ua kom tsis txhob ceeb toom ntawm cov kab ntawm cov av nplaum thiab tiv thaiv kev pheej hmoo ntawm cov kab mob uas tsis ruaj khov thiab cov yeeb nkab hlau.
• Av nplaum stabilization: CMC stampilizes rureighers cov minerals hauv cov minery, kev tsiv teb tsaws, thiab txhim kho kev ua haujlwm hauv av nplaum-nplua nuj.

2. Cov kua dej ua tiav:

• Kev tswj cov dej: CMC ntxiv rau kev ua tiav cov kua dej los tswj cov kua dej poob rau hauv kev tsim kom muaj kev ua tiav thaum ua tiav thiab cov haujlwm ua haujlwm. Nws pab tswj kev tsim kev ncaj ncees thiab tiv thaiv kev tsim kev puas tsuaj.
• SHATE STABILISION: CMC pab hauv cov stabilizing sales thiab kev tiv thaiv shale hydration thiab o thaum ua tiav kev ua haujlwm, txo cov khoom lag luam zoo thiab txhim kho cov khoom lag luam zoo.
• Lim Ncuav mog qab zib tsim: CMC txhawb nqa kev tsim ntawm cov khaub ncaws hnav, cov roj ntsha tsis zoo ntawm lub ntsej muag tsim, txo cov kua dej sib txawv rau hauv kev tsim.

3. MAUSESING SURRURRY:

• Thaum cov kua dej ntxiv ntxiv: CMC pabcuam ua cov dej uas txo qis rau hauv cov khoom noj kom tsawg thiab txhim kho MAAs tso. Nws pab kom ua raws li qhov kev sib cais zonal thiab cov cement.
• Thickening tus neeg sawv cev: CMC ua raws li tus neeg sawv cev tuab ntawm cov cement slurries, muab viscosity tswj thiab kev hloov pauv ntawm cov pajas ua rau thaum tso.
• Rheology kho mob: CMC hloov kho cov rheology ntawm cov cement slurries, txhim kho cov khoom txaus, sag tiv taus, thiab kev ruaj khov nyob hauv qab cov kev mob qis qis.

4. Txhim kho roj rov qab (EOR):

• Water Flooding: CMC is used in water flooding operations to enhance sweep efficiency and improve oil recovery from reservoirs. Nws nce qhov viscosity ntawm kev txhaj tshuaj dej, txhim kho kev tswj kev mus muaj zog thiab kev hloov chaw.
• Polymer Dej nyab: Hauv cov ntawv thov dej nyab polymer

5. Fracturing Dej:

• Cov kua dej viscosifier: CMC tau siv raws li tus neeg sawv cev viscosifying hauv cov kua dej hauv cov roj ntsha kom ua kom cov kua dej viscosity thiab tus tswv nqa nqa muaj peev xwm. Nws pab tsim thiab tswj kev ua pob txha lov rau hauv kev tsim thiab txhim kho kev thauj mus los thiab tso.
• Kev ua kom tawg ua tiav: CMC AIDS hauv kev tswj cov ntawv xa khoom plig ncaj ncees thiab ua kom txo cov kua dej thiab tiv thaiv kev txhawb nqa.

Hauv cov ntsiab lus xaus,Carboxymethyl cellulose(CMC) ua si lub luag haujlwm tseem ceeb hauv ntau cov ntawv thov hauv cov roj av, suav nrog cov kua dej ua kom tiav, ua kom cov roj rov qab), thiab fracturing kua. Nws cov vagatility raws li cov kua dej tsis tswj hwm, shale inhibitor, thiab rheology kho kom zoo ntxiv rau kev ua haujlwm tau zoo thiab vam meej oilfield.
