PAC-LV, PAC-Hv, PAC R, Roj Drilling Khoom

Polyanionic cellulose (PAC) feem ntau categorized rau hauv cov qib sib txawv raws li nws qhov hnyav molecular, qib kev hloov pauv, thiab lwm yam khoom. Nov yog qhov kev tawg ntawm qee hom PAC siv hauv kev lag luam roj drilling:

1. PAC-LV (Low Viscosity):
   • PAC-LV yog qib qis viscosity ntawm polyanionic cellulose siv hauv cov dej hauv cov dej drilling.
   • Nws yog tus cwj pwm los ntawm nws cov viscosity qis dua piv rau lwm qib PAC.
   • PAC-LV feem ntau yog siv thaum nruab nrab viscosity tswj thiab kev tswj tsis tau dej yuav tsum tau ua hauv kev ua haujlwm drilling.
2. PAC-HV (High Viscosity):
   • PAC-HV yog qib siab viscosity ntawm polyanionic cellulose siv rau kev ua tiav cov viscosity siab dua hauv cov dej hauv cov dej drilling.
   • Nws muab cov khoom zoo rheological thiab kev tswj tsis tau dej, ua rau nws tsim nyog rau kev sib tw drilling cov xwm txheej uas yuav tsum tau muaj kev ncua ntxiv ntawm cov khib nyiab.
3. PAC R (Regular):
   • PAC R, los yog qib PAC, yog qib nruab nrab viscosity ntawm polyanionic cellulose.
   • Nws muaj qhov sib npaug viscosifying thiab kua dej poob tswj cov khoom, ua rau nws tsim nyog rau ntau hom kev siv drilling qhov twg yuav tsum muaj viscosity nruab nrab thiab cov dej tsis zoo.

Cov qib sib txawv ntawm PAC no yog siv rau hauv cov roj drilling kua kom ua tiav cov viscosity, rheology, thiab cov kua dej poob tswj lub hom phiaj raws li cov txheej txheem drilling, tsim cov yam ntxwv, thiab kev ruaj ntseg zoo.

Hauv kev lag luam roj drilling, PAC yog siv los ua ib qho tseem ceeb ntxiv rau hauv cov dej-raws li drilling kua rau:

• Tswj viscosity thiab rheology kom optimize drilling kev ua tau zoo thiab tiv thaiv kom tsis txhob muaj qhov tsis zoo.
• Txo cov dej poob rau hauv kev tsim, txo qhov tsim kev puas tsuaj thiab txhim kho cov khoom tsim tau zoo.
• Ncua drilled cuttings thiab khib nyiab, yooj yim tshem tawm lawv los ntawm lub qhov dej.
• Muab lubrication thiab txo kev sib txhuam ntawm txoj hlua laum thiab cov phab ntsa zoo.

Zuag qhia tag nrho, PAC ua lub luag haujlwm tseem ceeb ua tus viscosifier thiab cov kua dej poob tswj tus neeg sawv cev hauv cov dej hauv cov dej drilling, ua rau muaj txiaj ntsig zoo thiab ua tiav kev ua haujlwm hauv kev lag luam roj thiab roj.
