Polyanionic cellulose (PAC) ndi polima wosungunuka m'madzi womwe umagwiritsidwa ntchito kwambiri mumakampani amafuta monga chowonjezera chobowola madzimadzi. Ndi polyanionic yochokera ku cellulose, yopangidwa ndi kusintha kwa mankhwala a cellulose ndi carboxymethyl. PAC ili ndi zinthu zabwino kwambiri monga kusungunuka kwamadzi kwambiri, kukhazikika kwamafuta, komanso kukana kwa hydrolysis. Izi zimapangitsa PAC kukhala chowonjezera choyenera pakubowola makina amadzimadzi pofufuza ndi kupanga mafuta.
Kugwiritsa ntchito PAC pobowola mafuta makamaka chifukwa chakutha kuwongolera kukhuthala ndi kusefera kwamadzi obowola. Kuwongolera ma viscosity ndikofunikira kwambiri pakubowola chifukwa kumakhudza kuyendetsa bwino komanso chitetezo. Kugwiritsa ntchito PAC kumathandiza kukhazikika kwa mamasukidwe akayendedwe amadzimadzi obowola, omwe ndi ofunikira kwambiri kuti apitilize kuyenda kwamadzi obowola. Kukhuthala kwamadzimadzi obowola kumayendetsedwa ndi kuchuluka kwa PAC komwe amagwiritsidwa ntchito komanso kulemera kwa polima. Molekyu ya PAC imagwira ntchito ngati thickener, kapena viscosifier, chifukwa imawonjezera kukhuthala kwamadzi obowola. The mamasukidwe akayendedwe a pobowola madzimadzi zimadalira PAC ndende, mlingo wa m'malo ndi maselo kulemera.
Kuwongolera kusefa ndi chinthu china chofunikira pakubowola. Kusefera kumayenderana ndi kuchuluka kwa madzimadzi omwe amalowera khoma la chitsime pobowola. Kugwiritsa ntchito PAC kumathandizira kuwongolera kusefera ndikuchepetsa kulowerera kwamadzi. Kulowetsedwa kwamadzimadzi kungayambitse kutayika kwa ma circulation, kuwonongeka kwa mapangidwe komanso kuchepetsa kubowola bwino. Kuphatikiza PAC kumadzimadzi obowola kumapanga mawonekedwe ngati gel omwe amakhala ngati keke yosefera pamakoma a chitsime. Keke ya fyulutayi imachepetsa kulowetsedwa kwamadzimadzi, kumathandiza kusunga kukhulupirika kwa chitsime ndikuchepetsa chiopsezo cha kuwonongeka kwa mapangidwe.
PAC imagwiritsidwanso ntchito kupititsa patsogolo mphamvu ya shale yamadzi akubowola. Kuponderezedwa kwa shale ndikutha kwa madzi obowola kuti ateteze shale yokhazikika kuti isatuluke komanso kutupa. Kuchuluka kwa madzi ndi kukulitsa kwa shale kungayambitse mavuto monga kusakhazikika kwa chitsime, kutsekeka kwa mipope, komanso kutayika kwa madzi. Kuwonjezera PAC kumadzimadzi obowola kumapanga chotchinga pakati pa shale ndi madzi obowola. Chotchinga ichi chimathandiza kusunga umphumphu wa khoma la chitsime pochepetsa hydration ndi kutupa kwa shale.
Kugwiritsanso ntchito kwina kwa PAC pakubowola mafuta kuli ngati chowonjezera chochepetsa kutaya madzi. Kutayika kwa kusefera kumatanthauza kutayika kwa madzi obowola omwe amalowa m'mapangidwe pobowola. Kutayika kumeneku kungayambitse kuwonongeka kwa mapangidwe, kutayika kwa kayendedwe kake komanso kuchepa kwa ntchito yoboola bwino. Kugwiritsa ntchito PAC kumathandizira kuchepetsa kutayika kwamadzimadzi popanga keke yosefera pamakoma a chitsime omwe amalepheretsa kutuluka kwamadzi kulowa mu mapangidwe. Kutsika kwamadzimadzi kumathandizira kusunga umphumphu wa wellbore ndikuwongolera kubowola bwino.
PAC itha kugwiritsidwanso ntchito kupititsa patsogolo kukhazikika kwamadzi akubowola. Kukhazikika kwa Wellbore kumatanthauza kuthekera kwamadzimadzi obowola kuti asungike bwino pobowola. Kugwiritsa ntchito PAC kumathandizira kukhazikika kwa khoma lachitsime popanga keke yosefera pakhoma la chitsime. Keke ya fyulutayi imachepetsa kulowerera kwamadzi mu khoma ndikuchepetsa chiopsezo cha kusakhazikika kwa Wellbore.
Kugwiritsa ntchito polyanionic cellulose pobowola mafuta kumapereka maubwino ambiri. PAC imagwiritsidwa ntchito kuwongolera kukhuthala ndi kusefera kwamadzi obowola, kuwongolera magwiridwe antchito a shale, kuchepetsa kutayika kwa kusefera, ndikuwongolera kukhazikika kwa chitsime. Kugwiritsa ntchito PAC pakubowola mafuta kumathandizira kukulitsa magwiridwe antchito ndikuchepetsa chiwopsezo cha kuwonongeka kwa mapangidwe, kutayika kwakuyenda komanso kusakhazikika kwabwino. Chifukwa chake, kugwiritsa ntchito PAC ndikofunikira kwambiri pakubowola ndi kupanga mafuta.
