Polyanionic Cellulose (Pac) inzvimbo ine mvura-yemvura yakashandiswa zvakanyanya muindasitiri yepeturu seyakaomeswa. Iyo polyanionic inobva cellulose, synthesised nemakemikari kugadziridzwa kwe cellbolose ine carboxymethyl. Pac ine zvinhu zvakanakisa senge zvakakwirira zvemvura solubility, kugadzikana kwekunyora, uye hydrolyis kuramba. Izvi zvivakwa zvinoita kuti pac yakanakira yekukwevera kwehurongwa hwemvura mukuongorora kwepeturu uye kugadzirwa.
Iko kushandiswa kwePAC mumafuta ekudhiraini kunonyanya kukonzerwa nekugona kwayo kudzora viscosity uye fillration zvivakwa zvekukwevera mvura. Viscosity Kudzora chinhu chakanyanya kutsoropodza mukukwezva mashandiro sezvazvinobata zvinobudirira uye kuchengeteka. Iko kushandiswa kwePAC kunobatsira kusimbisa viscosity yekukweva kwemvura, iyo yakakosha kuchengetedza iyo yekuyerera midziyo yekukwevera kwemvura. Iyo viscosity yekukweva kwemvura inodonha ichidzorwa neyekuvanzika kwePac yakashandiswa uye iyo smecular uremu hwe polymer. Iyo Pac Molecule inoshanda seyakakwenenzverwa, kana viscosfier, nekuti inowedzera iyo viscosity yekukwevera mvura. Iyo viscosity yekukwevera mvura inoenderana nePac yekuvhara, degree rekutsiva uye rinonzwika uremu.
Filtation kudzora chimwe chinhu chakakomba chekudzvinyirira mabasa ekudhirowa. Kuita kwefaira kunoenderana nehuwandu hwaipinda mumvura madziro panguva yekudhirowa. Uchishandisa Pac Inobatsira Kuvandudza Kwekutanga Kudzora uye kuderedza kupindira kwemvura. Fluid intrusion inogona kutungamira pakurasikirwa kwekutenderera, kukuvadzwa kwekukuvara uye kuderedzwa kuderedza kushanda zvakanaka. Kuwedzera pac kumvura yekukwevera inogadzira chimiro chemagira-semaitiro chinoita sekeke faira pamadziro ekare. Iyi kiredhiti yefaira inoderedza fluid fluid, inobatsira kuchengetedza kutendeka kweiyo turbord uye kuderedza njodzi yekukuvara kwekugadzira.
Pac inoshandiswawo kuvandudza iyo shale kudzvanywa zvivakwa zvekukwevera mvura. Shale kukurumidza ndiko kugona kwekukwevera mvura yekudzivisa shale kubva ku hydrating uye kuzvimba. Hydration uye kuwedzera kweiyo shale inoshanda kunogona kutungamira kumatambudziko akadai semagetsi kusagadzikana, pombi yakanamatira, uye yakarasika kutenderera. Kuwedzera pac kune iyo yekukwevera fluid inogadzira chipinganidzo pakati pesimbe uye mvura yekukwevera. Ichi chipinganidzo chinobatsira kuchengetedza kutendeka kwemadziro ehuremu nekudzora hydration uye kuzvimba kwesimbe.
Imwe application yePAC mumafuta yekudhara yakaita sekurasikirwa kwemvura kuderedza. Kufema kweFilt kunoreva kurasikirwa kwekukwevera mvura yekukwevera mvura ichipinda muumbi panguva yekudhirowa. Uku kurasikirwa kunogona kutungamira kukuvadzwa kwekugadzira, kuparadzwa kwekutenderera uye kuderedza zvinobudirira. Iko kushandiswa kwePAC kunobatsira kuderedza kurasikirwa kwemvura nekugadzira iyo keke yefaira pamadziro ehurombo iyo inovhara mvura yekuyerera. Yakadzikira kurasikirwa kurasikirwa kunobatsira kuchengetedza kutendeka kwakanaka uye kunovandudza kudhiraivha.
Pac inogona zvakare kushandiswa kuvandudza kugadzikana kwellwel yekukwevera kwemvura. Wellbore kutadza kunoreva kugona kwekukwezva mvura yekukwevera kuti ichengetedze kusimba kwenguva refu panguva yekukwevera. Iko kushandiswa kwePAC kunobatsira kusimbisa rusvingo rwese nekugadzira keke yefaira pamusvingo. Iyi kiredhiti yefaira inoderedza fluid fluid kupinda mumadziro uye inoderedza njodzi yekusagadzikana kwakanaka.
Iko kushandiswa kwePolyanionic Cellulose mukukwezva kwemafuta kunopa zvakawanda zvakanaka. Pac inoshandiswa kudzora viscosity uye kuita kwesimbi yekukwevera kwemvura, kugadzirisa shale inhibition performance, kuderedza kurasikirwa kwefletration, uye kugadzirisa hutano hwakanaka. Iko kushandiswa kwePac mumvura yekukwevera kwemafuta kunobatsira kuwedzera kugona uye kuderedza njodzi yekukuvara kwekugadzira, yakarasika kutenderera nekusagadzikana uye zvakanaka kusagadzikana. Naizvozvo, kushandiswa kwePac kwakakosha kubudirira kwemafuta ekukwevera kwemafuta nekugadzira.
