Carboxymethyl cellulose (cmc) yog cov molecular siab polymer dav siv nyob rau hauv cov kua hluav taws xob nrog cov khoom muaj kuab zoo thiab ruaj khov. Nws yog cov cellulose hloov, feem ntau yog tsim los ntawm kev rov qab cellulose nrog chloroacetic acid. Vim nws cov kev ua tau zoo, CMC tau siv dav hauv ntau daim teb xws li roj drilling, tsuas, kev tsim kho thiab khoom noj khoom haus.
1. Cov khoom ntawm CMC
Carboxymethyl cellulose yog ib tug dawb rau lub teeb daj hmoov uas tsim ib lub pob tshab colloidal tov thaum yaj hauv dej. Nws cov qauv siv tshuaj muaj cov roj carboxymethyl, uas ua rau nws muaj zoo hydrophilicity thiab lubricity. Tsis tas li ntawd, lub viscosity ntawm cmc tuaj yeem tswj hwm los ntawm kev kho nws cov molecular hnyav thiab kev ua kom haum rau hauv cov kua drilling tau hloov tau.
2. Lub luag haujlwm hauv cov kua dej drilling
Thaum lub sij hawm drilling txheej txheem, kev ua yeeb yam ntawm drilling cov kua yog qhov tseem ceeb. CMC ua cov luag haujlwm hauv qab no hauv cov dej lim dej:
Thickener: CMC tuaj yeem nce viscosity ntawm drilling dej, yog li txhim kho lawv txoj kev nqa khoom, ua kom muaj peev xwm tshem tawm cov khoom muaj zog, thiab tiv thaiv cov khoom ua kom tsis txhob muaj zog, thiab tiv thaiv cov khoom ua kom tsis txhob muaj zog, thiab tiv thaiv kom tsis txhob muaj peev xwm ua kom muaj zog, thiab tiv thaiv cov khoom ua kom tsis txhob muaj zog, thiab tiv thaiv cov khoom ua kom tsis txhob muaj zog, thiab tiv thaiv kom tsis txhob muaj peev xwm ua kom muaj txiaj ntsig, thiab tiv thaiv cov khoom ua kom tsis txhob muaj zog, thiab tiv thaiv cov khoom ua kom tsis txhob muaj zog, thiab tiv thaiv cov khoom ua kom tsis txhob muaj zog, thiab tiv thaiv cov khoom ua kom tsis txhob muaj zog, thiab tiv thaiv cov khoom ua kom tsis txhob muaj txiaj ntsig, thiab tiv thaiv cov khoom ua kom tsis txhob muaj zog, thiab tiv thaiv kom tsis txhob muaj peev xwm ua kom cov khoom noj.
Rheology kho mob: los ntawm kev kho cov khoom siv hluav taws xob rhealological ntawm cov kua dej drilling, cm thiaj li nws tseem tuaj yeem tswj cov dej zoo nyob rau hauv kev kub siab thiab siab siab.
Plug Tus Neeg Sawv Cev: CMC cov lus tuaj yeem sau cov pob zeb tawg, zoo txo cov dej poob thiab txhim kho kev nqus dej.
Cov roj nplua nyeem: Ntxiv rau ntawm CMC tuaj yeem txo cov kev sib txhuam ntawm lub laum me ntsis thiab phab ntsa zoo, txo cov ntoo kom zoo thiab nce kev hnav khaub ncaws.
3. Qhov zoo ntawm CMC
Siv Carboxymethyl cellulose raws li cov kua dej txuas ntxiv muaj cov txiaj ntsig hauv qab no:
Cov phooj ywg ib puag ncig: CMC yog cov khoom siv polymer uas muaj cov khoom siv biodegradity thiab me ntsis rau ib puag ncig.
Nqi-txiaj ntsig: piv nrog lwm cov hluavtaws polymers, cmc muaj tus nqi qis dua, kev ua tau zoo thiab muaj txiaj ntsig zoo.
Qhov kub thiab txias thiab salinity hloov tau: cms tseem tuaj yeem tswj tau ruaj khov nyob rau hauv ib puag ncig kub thiab zoo ntsev thiab hloov rau ntau yam ntawm geological.
4. Thov piv txwv
Hauv cov ntawv thov tiag tiag, ntau lub tuam txhab roj roj tau ua tiav cmc rau cov haujlwm sib txawv. Piv txwv li, hauv qee qhov kub thiab kub siab thiab muaj txiaj ntsig zoo ntawm CMC muaj peev xwm tswj tau cov rheology ntawm cov av nkos thiab ua kom muaj qhov khiav ceev. Tsis tas li ntawd, hauv qee cov kev tsim cov nyom, uas siv CMC ua lub ntsaws tus neeg sawv cev tuaj yeem txo qis kev ua tau zoo thiab txhim kho drilling efficiency.
5. Kev ceev faj
Txawm hais tias CMC muaj ntau yam zoo, cov ntsiab lus hauv qab no yuav tsum tau sau tseg thaum siv:
Kev faib tawm: Kho tus nqi ntawm cmc ntxiv raws li qhov tseeb. Kev siv ntau dhau yuav ua rau muaj kev txo qis fuubly.
Kev Cia Yuav Tsum: Nws yuav tsum khaws cia rau hauv ib puag ncig qhuav thiab txias kom tsis txhob muaj kev ya raws kev ua tau zoo.
Sib tov tusyees: thaum npaj cov kua drilling, xyuas kom tiav tias CMC yog yaj tag nrho kom tsis txhob muaj particle sib cais.
Daim ntawv thov ntawm carboxymethyl cellulose hauv drilling kua tsis tsuas yog txhim kho cov nqi, tab sis kuj txhawb kev tiv thaiv kev tiv thaiv ib puag ncig thev naus laus zis rau ib qho. Nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, daim ntawv thov tau txuas ntxiv, thiab peb tos kom ua si lub luag haujlwm ntau dua hauv cov haujlwm tom ntej drilling.
