PAC Daim Ntawv Thov ntawm Drilling thiab Qhov Zoo Sinking ntawm Roj av

Polyanionic cellulose (PAC) yog dav siv nyob rau hauv lub drilling thiab zoo sinking txheej txheem ntawm cov av nkos vim nws zoo heev zog thiab functionalities. Nov yog qee qhov kev siv tseem ceeb ntawm PAC hauv kev lag luam no:

1. Viscosity Control: PAC yog siv los ua tus hloov kho rheology hauv cov kua dej los tswj cov viscosity thiab tswj cov kua dej kom zoo. Nws pab tswj tus cwj pwm ntws ntawm cov av nkos drilling, kom ntseeg tau tias qhov zoo tshaj plaws viscosity rau kev ua haujlwm zoo drilling. PAC yog tshwj xeeb tshaj yog zoo nyob rau hauv high-temperature thiab high-pressure drilling ib puag ncig uas ruaj khov viscosity yog ib qho tseem ceeb rau wellbore stability thiab lub qhov ntxuav.
2. Fluid Loss Control: PAC ua raws li tus neeg saib xyuas kev poob dej, tsim cov ncuav mog qab zib nyias, impermeable lim rau ntawm phab ntsa hauv lub qhov dej kom tsis txhob muaj dej ntau dhau rau hauv kev tsim. Qhov no pab tswj kom muaj kev ncaj ncees zoo, tswj kev tsim kev puas tsuaj, thiab txo qis kev tsim cov dej ntxeem tau. PAC-raws li drilling kua muab kev txhim kho pom kev, txo qhov kev pheej hmoo ntawm kev sib txawv ntawm qhov sib txawv thiab cov teeb meem poob.
3. Shale Inhibition: PAC inhibits shale o thiab dispersion los ntawm kev tsim cov txheej tiv thaiv ntawm shale nto, tiv thaiv hydration thiab disintegration ntawm shale hais. Qhov no yuav pab kom ruaj khov shale formations, txo qhov zoo ntawm qhov tsis ruaj khov, thiab txo qis kev phom sij xws li cov yeeb nkab daig thiab qhov dej ntws tawm. PAC-raws li drilling kua siv tau nyob rau hauv ob qho tib si dej-raws li thiab roj-raws li drilling ua hauj lwm.
4. Kev ncua thiab txiav kev thauj mus los: PAC txhim kho qhov kev ncua thiab kev thauj mus los ntawm cov drilled cuttings nyob rau hauv cov dej drilling, tiv thaiv lawv qhov chaw thiab tsub zuj zuj nyob rau hauv qab ntawm lub qhov dej. Qhov no ua kom yooj yim tshem tawm cov khoom drilled los ntawm lub qhov dej, txhawb kev tu lub qhov zoo dua thiab tiv thaiv cov blockages hauv cov khoom siv drilling. PAC txhim kho lub peev xwm nqa thiab kev ua haujlwm ntawm cov dej drilling, ua rau kev ua haujlwm zoo dua qub thiab txhim kho kev ua haujlwm tag nrho.
5. Kub thiab Salinity Stability: PAC nthuav tawm kev ruaj ntseg zoo tshaj plaws ntawm ntau qhov kub thiab txias qib uas tau ntsib hauv kev ua haujlwm roj thiab roj. Nws tuav nws cov kev ua tau zoo thiab kev ua tau zoo nyob rau hauv qhov hnyav drilling ib puag ncig, suav nrog kev sib sib zog nqus dej, kev sib tsoo ntawm ntug dej hiav txwv, thiab cov ntawv thov tsis sib xws. PAC pab txo cov dej degradation thiab tswj xyuas cov dej zoo sib xws hauv cov xwm txheej nyuaj.
6. Environmental Compliance: PAC yog ib puag ncig tus phooj ywg thiab biodegradable, ua rau nws yog ib qho kev xaiv zoo rau drilling kua formulations nyob rau hauv ib puag ncig rhiab heev. Nws ua raws li cov kev cai ib puag ncig thiab cov qauv, txo qhov cuam tshuam ntawm kev ua haujlwm drilling ntawm ib puag ncig ecosystem. PAC-raws li cov kua dej drilling muaj cov kev daws teeb meem zoo rau kev tshawb nrhiav roj thiab roj thiab kev tsim khoom.

polyanionic cellulose (PAC) plays lub luag haujlwm tseem ceeb hauv cov txheej txheem drilling thiab ua kom zoo ntawm cov av nkos los ntawm kev muab cov viscosity tswj, tswj cov dej tsis zoo, shale inhibition, ncua kev txiav, txiav kev thauj mus los, qhov kub thiab txias, thiab kev ua raws li ib puag ncig. Nws versatility thiab kev ua tau zoo ua rau nws yog ib qho tseem ceeb additive nyob rau hauv drilling kua formulations, pab rau kev nyab xeeb, zoo, thiab nqi-zoo drilling kev lag luam nyob rau hauv cov roj thiab roj kev lag luam.
