Polyanionic Cellulose (PAC)

Polyanionic Cellulose (PAC) yog cov dej-soluble cellulose derivative uas yog dav siv nyob rau hauv ntau yam lag luam rau nws cov khoom rheological thiab kua tsis muaj peev xwm tswj tau.Nws yog muab los ntawm tej yam ntuj tso cellulose los ntawm ib tug series ntawm tshuaj hloov kho, ua rau ib tug polymer nrog anionic nqi raws cellulose qaum.Nov yog qee cov ntsiab lus tseem ceeb ntawm Polyanionic Cellulose:

1. Chemical Structure: PAC yog chemically zoo ib yam li cellulose tab sis muaj anionic carboxyl pawg (-COO-) txuas rau cellulose qaum.Cov pab pawg anionic no muab PAC nrog nws cov khoom tshwj xeeb, suav nrog dej solubility thiab muaj peev xwm cuam tshuam nrog lwm cov molecules los ntawm kev sib cuam tshuam electrostatic.
2. Kev ua haujlwm: PAC feem ntau yog siv los ua tus hloov kho rheology thiab tus neeg saib xyuas kev poob dej hauv cov dej drilling rau kev tshawb nrhiav roj thiab roj.Nws pab tswj cov viscosity thiab ntws cov khoom ntawm cov kua dej drilling, txhim kho kev ncua ntawm cov khib nyiab, thiab txo cov kua dej poob rau hauv cov txheej txheem ntxeem tau.PAC kuj tseem txhim kho lub qhov ntxuav thiab tiv thaiv qhov tsis zoo ntawm qhov dej thaum lub sijhawm ua haujlwm drilling.
3. Daim ntaub ntawv: Daim ntawv thov tseem ceeb ntawm PAC yog nyob rau hauv kev lag luam roj thiab roj, qhov twg nws yog siv nyob rau hauv drilling av nkos formulations.Nws yog feem ntau ua hauj lwm nyob rau hauv ob qho tib si dej-raws li thiab roj-raws li drilling kua rau optimize kev ua tau zoo thiab xyuas kom meej drilling efficiency.PAC kuj tseem siv rau hauv lwm qhov kev lag luam rau nws cov thickening, stabilizing, thiab dej tuav cov khoom nyob rau hauv ntau yam formulations.
4. Hom: PAC muaj nyob rau hauv ntau qib thiab viscosities kom haum rau cov ntawv thov tshwj xeeb.Cov hom PAC feem ntau suav nrog cov qib qis viscosity rau kev tswj cov kua dej tsis zoo thiab qib siab viscosity rau kev hloov kho viscosity thiab tshem tawm cov khib nyiab hauv cov kua dej drilling.Kev xaiv ntawm PAC hom nyob ntawm cov yam ntxwv xws li cov xwm txheej zoo, qhov chaw drilling, thiab cov kua dej tshwj xeeb.
5. Qhov zoo: Kev siv PAC muaj ntau qhov zoo hauv kev ua haujlwm drilling, suav nrog:
   • Cov kua dej tsis zoo tswj kom muaj kev ruaj ntseg zoo thiab tiv thaiv kev tsim kev puas tsuaj.
   • Txhim kho qhov kev ncua ntawm kev xyaum txiav thiab cov khib nyiab, ua rau kev tu lub qhov zoo dua.
   • Txhim kho cov khoom rheological, ua kom cov kua dej ua tau zoo nyob rau hauv qhov sib txawv ntawm qhov downhole.
   • Compatibility nrog rau lwm yam additives thiab drilling kua Cheebtsam, yooj yim formulation customization thiab optimization.
6. Kev txiav txim siab ib puag ncig: Thaum PAC tau siv dav hauv cov dej drilling, nws cov kev cuam tshuam ib puag ncig thiab biodegradability yuav tsum raug txiav txim siab.Kev siv zog tab tom txhim kho ib puag ncig tus phooj ywg lwm txoj hauv kev rau PAC thiab txo qis nws ib puag ncig hneev taw hauv kev ua haujlwm drilling.

Polyanionic Cellulose (PAC) yog ntau yam thiab tseem ceeb additive nyob rau hauv cov roj thiab roj kev lag luam, qhov uas nws plays lub luag hauj lwm tseem ceeb nyob rau hauv optimizing drilling kua dej kev ua tau zoo thiab xyuas kom meej drilling efficiency.Nws cov khoom tshwj xeeb rheological, kua dej tsis muaj peev xwm tswj tau, thiab kev sib raug zoo ua rau nws muaj txiaj ntsig zoo hauv kev tsim cov av nkos.
