CMC siv hauv cov roj av thiab roj kev lag luam

Carboxymetylcelleculose (CMC) tau siv dav hauv cov roj av thiab roj drilling kev lag luam rau ntau yam kev siv vim nws cov khoom siv dej-soluble. Nws yog muab los ntawm cellulose, lub ntuj polymer pom nyob rau hauv cov nroj tsuag, los ntawm cov txheej txheem tshuaj lom neeg uas qhia cov pawg carboxymethyl. CMC tau ua haujlwm hauv ob qho tib si onshore thiab offshore drilling ua haujlwm. Ntawm no yog ob peb qhov tseem ceeb siv ntawm CMC nyob rau hauv cov roj av thiab roj drilling kev lag luam:

1. DRILLING FRLDITATE:
   • CMC yog feem ntau siv ua ib qho tseem ceeb ntxiv hauv cov kua dej drilling. Nws pab ntau lub hom phiaj, suav nrog:
     • Viscosifier: CMC nce lub viscosity ntawm drilling kua, muab qhov tsim nyog siv lub cev thiab ncua kev txiav tawm.
     • Kev tswj cov kua dej: CMC pab tswj cov kua dej los mus rau kev tsim, ua kom muaj kev ruaj ntseg ntawm qhov chaw nyob ntawm qhov chaw nyob.
     • Rheology kho mob: CMC ua raws li kev hloov kho rheology, muaj kev cuam tshuam nrog cov khoom muaj dej ntawm cov khoom siv sib txawv.
2. Tus neeg raug tshem tawm:
   • Hauv cov kua dej hnyiab, CMC ua raws li tus neeg sawv cev rov qab, tiv thaiv cov khoom siv tsis raug, xws li tho kev txiav, los ntawm kev sib tw hauv qab ntawm qhov chaw nkaum ntawm qhov chaw nkaum. Qhov no pab tau drilling thiab tshem tawm ntawm cuttings los ntawm lub borehole.
3. Roj nplua nyeem thiab kev sib txhuam reducer:
   • CMC muab lubrication thiab ua hauj lwm li kev sib txhuam reducer hauv cov kua drilling. Qhov no yog qhov tseem ceeb rau kev txo kev sib txhuam ntawm cov laum me ntsis thiab lub borehole, txo cov hnav rau ntawm cov khoom siv drilling thiab txhim kho kev drilling kev ua tau zoo.
4. Borehole stabilization:
   • CMC pab tswj qhov chaw ua haujlwm ntawm kev tiv thaiv los ntawm kev tiv thaiv lub cev qhuav dej ntawm cov kev sib tsoo. Nws tsim cov txheej txheem tiv thaiv ntawm phab ntsa zoo, ua kom muaj kev ruaj khov thaum lub sijhawm ua haujlwm drilling.
5. Maas Slurry Ntxiv Ntxiv:
   • CMC yog siv los ua kev ntxiv nyob rau hauv Maas slurries rau cov roj zoo centeing. Nws txhim kho cov khoom sib dhos ntawm cov cement slurry, kom ua kom muaj kev tso ua ke zoo thiab tiv thaiv kev sib cais ntawm cov cement.
6. Txhim kho cov roj rov qab (EOR):
   • Hauv kev txhim kho cov roj rov qab ua ke, cmc tuaj yeem siv ua tus neeg sawv cev tswj tau. Nws yuav pab txhim kho kev tshem tawm kev ua haujlwm ntawm cov kua dej txhaj, yooj yim txoj kev rov qab ntawm cov roj ntxiv los ntawm cov dej hauv dej.
7. Flu viscosity tswj:
   • CMC tau ua haujlwm los tswj cov viscosity ntawm drilling kua, kom ua kom cov kua dej zoo tshaj plaws nyob hauv qab cov kev mob sib txawv. Qhov no yog qhov tseem ceeb rau kev tswj cov kev ua haujlwm thiab muaj kev ruaj khov ruaj khov.
8. Lim ncuav mog qab zib tswj:
   • CMC pab tswj cov kev tsim ntawm lim ncuav ncuav ntawm phab ntsa zoo thaum lub qhov khiav. Nws pab txhawb rau kev tsim cov khoom noj ruaj khov thiab cov lim ntim cov lim, tiv thaiv kom tsis txhob muaj dej ntau dhau los thiab tswj hwm kev ncaj ncees.
9. Reservoir Drilling kua:
   • Nyob rau hauv reservoir drilling, cmc yog siv nyob rau hauv drilling kua los daws cov kev cov nyom uas cuam tshuam nrog cov dej num. Nws pab hauv kev saib xyuas qhov ruaj ntseg ntawm qhov muaj kev nyab xeeb thiab cov tshuaj ua kua.
10. Lub Neej Kev Tswj:
    • CMC tau ua haujlwm rau kev tswj hwm kev teeb meem ntawm kev sib ncig thaum lub sijhawm khiav haujlwm. Nws pab muab foob rau cov choj thiab tus choj sib tsoo hauv kev tsim, tiv thaiv kom cov kev poob ntawm cov kua dej ua lossis thaj chaw ib cheeb tsam.
11. Zoo txhawb cov kua dej:
    • CMC tuaj yeem siv tau hauv cov kua hluav taws xob kom zoo los txhim kho cov kua viscosity thiab muab ncua cov pheeb suab thaum lub sijhawm ua haujlwm hydraulic.

Hauv cov ntsiab lus, carboxymethylcelleculose (cmc) plays ib qho tseem ceeb hauv cov roj av kev lag luam, ua rau muaj kev lag luam, ruaj khov, thiab kev nyab xeeb ntawm kev ua haujlwm drilling. Nws cov khoom muaj ntau yam ua rau nws muaj txiaj ntsig zoo ntxiv hauv cov kua dej drilling thiab MAAs slurring thiab MAAs slurries, hais ntau cov kev sib tw ntawm cov roj thiab roj peev.
