Carboxymethyl cellulose (CMC) yog ib lub siab molecular polymer dav siv nyob rau hauv drilling kua nrog zoo rheological zog thiab stability. Nws yog hloov kho cellulose, feem ntau tsim los ntawm reacting cellulose nrog chloroacetic acid. Vim nws qhov kev ua tau zoo heev, CMC tau siv dav hauv ntau qhov chaw xws li roj drilling, mining, kev tsim kho thiab kev lag luam khoom noj.
1. Cov khoom ntawm CMC
Carboxymethyl cellulose yog dawb mus rau lub teeb daj hmoov uas tsim cov pob tshab colloidal tov thaum yaj hauv dej. Nws cov qauv tshuaj muaj carboxymethyl pawg, uas ua rau nws muaj hydrophilicity zoo thiab lubricity. Tsis tas li ntawd, qhov viscosity ntawm CMC tuaj yeem tswj tau los ntawm kev kho nws qhov hnyav molecular thiab concentration, uas ua rau nws daim ntawv thov hauv cov dej drilling tau hloov tau yooj yim.
2. Lub luag haujlwm hauv cov kua dej drilling
Thaum lub sijhawm drilling txheej txheem, kev ua haujlwm ntawm cov kua dej drilling yog qhov tseem ceeb. CMC ua lub luag haujlwm tseem ceeb hauv qab no hauv cov dej drilling:
Thickener: CMC tuaj yeem ua kom cov viscosity ntawm cov dej drilling, yog li txhim kho lawv lub peev xwm nqa, khaws cov khoom raug tshem tawm, thiab tiv thaiv sedimentation.
Rheology modifier: Los ntawm kev kho cov rheological zog ntawm cov dej drilling, CMC tuaj yeem txhim kho nws cov fluidity kom nws tseem tuaj yeem tswj cov dej ntws zoo hauv qhov kub thiab txias.
Plug tus neeg saib xyuas: CMC hais tuaj yeem sau cov pob zeb tawg, txo cov dej tsis zoo thiab txhim kho kev ua haujlwm zoo.
Lubricant: Qhov sib ntxiv ntawm CMC tuaj yeem txo qhov kev sib txhuam ntawm cov laum me ntsis thiab cov phab ntsa zoo, txo qhov hnav thiab ua kom qhov drilling ceev.
3. Qhov zoo ntawm CMC
Siv carboxymethyl cellulose ua cov kua dej ntxiv muaj cov hauv qab no zoo:
Ib puag ncig tus phooj ywg: CMC yog cov khoom siv ntuj tsim polymer nrog biodegradability zoo thiab cuam tshuam me ntsis rau ib puag ncig.
Tus nqi-kev ua tau zoo: Piv nrog rau lwm cov khoom siv hluavtaws, CMC muaj tus nqi qis dua, kev ua haujlwm zoo heev thiab tus nqi siab.
Kub thiab salinity adaptability: CMC tseem tuaj yeem tswj kev ua haujlwm ruaj khov hauv qhov kub thiab txias ib puag ncig ntsev thiab hloov mus rau ntau yam geological.
4. Daim ntawv thov piv txwv
Hauv kev siv tiag tiag, ntau lub tuam txhab roj tau ua tiav CMC rau cov haujlwm sib txawv. Piv txwv li, nyob rau hauv qee qhov kub thiab txias qhov dej, ntxiv qhov tsim nyog ntawm CMC tuaj yeem tswj tau cov rheology ntawm cov av nkos thiab xyuas kom cov drilling du. Tsis tas li ntawd, nyob rau hauv ib co complex formations, siv CMC raws li ib tug plugging tus neeg sawv cev muaj peev xwm txo tau cov kua dej thiab txhim kho drilling efficiency.
5. Ceev faj
Txawm hais tias CMC muaj ntau qhov zoo, cov ntsiab lus hauv qab no yuav tsum tau sau tseg thaum siv:
Qhov Loj: Kho tus nqi ntawm CMC ntxiv raws li qhov tseeb. Kev siv ntau dhau tuaj yeem ua rau txo qis fluidity.
Cia tej yam kev mob: Nws yuav tsum tau khaws cia rau hauv ib qho chaw qhuav thiab txias kom tsis txhob ya raws cuam tshuam kev ua haujlwm.
Kev sib xyaw ua ke: Thaum npaj cov kua dej drilling, xyuas kom meej tias CMC tau yaj tag nrho kom tsis txhob muaj qhov sib xyaw ua ke.
Daim ntawv thov ntawm carboxymethyl cellulose nyob rau hauv drilling kua tsis tsuas yog txhim kho drilling efficiency thiab txo nqi, tab sis kuj txhawb kev loj hlob ntawm ib puag ncig tiv thaiv technology rau ib tug tej yam kev mob. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, daim ntawv thov ntawm CMC yuav nthuav dav ntxiv, thiab peb tos ntsoov yuav ua lub luag haujlwm ntau dua hauv cov haujlwm drilling yav tom ntej.
