Polyanionic cellulose (PAC) ni polymer ishongesha amazi ikoreshwa cyane mu nganda za peteroli nk'inyongeramusaruro y'amazi yo gucukura. Ni polyanionic ikomoka kuri cellulose, ikorwa binyuze mu guhindura cellulose hifashishijwe karuboksimetili. PAC ifite imiterere myiza nko gushonga cyane mu mazi, kudahinduka kw'ubushyuhe, no kudahinduka kwa hydrolysis. Iyi miterere ituma PAC iba inyongeramusaruro nziza mu gucukura amazi mu bushakashatsi no mu gukora peteroli.
Ikoreshwa rya PAC mu gucukura peteroli ahanini riterwa n'ubushobozi bwayo bwo kugenzura ubukana n'imikorere yo kuyungurura by'amazi yo gucukura. Kugenzura ubukana ni ikintu cy'ingenzi mu bikorwa byo gucukura kuko bigira ingaruka ku musaruro n'umutekano wo gucukura. Gukoresha PAC bifasha mu kugabanya ubukana bw'amazi yo gucukura, ari ingenzi cyane mu kubungabunga imiterere y'amazi yo gucukura. Ubukana bw'amazi yo gucukura bugenzurwa n'ubwinshi bwa PAC ikoreshwa n'uburemere bwa molekile ya polymer. Molekile ya PAC ikora nk'ikintu gikomeza ubukana, cyangwa viscosifier, kuko yongera ubukana bw'amazi yo gucukura. Ubukana bw'amazi yo gucukura buterwa n'ubwinshi bwa PAC, urwego rw'ubusimbuza n'uburemere bwa molekile.
Kugenzura uburyo amazi ayungururwa ni ikindi kintu cy'ingenzi mu bikorwa byo gucukura. Imikorere y'uburyo amazi ayungururwa ifitanye isano n'umuvuduko w'amazi yinjira mu rukuta rw'iriba mu gihe cyo gucukura. Gukoresha PAC bifasha kunoza uburyo amazi ayungururwa no kugabanya uburyo amazi yinjira. Uburyo amazi yinjira mu iriba bushobora gutuma amaraso atakaza uruziga, kwangirika kw'ibyiciro no kugabanya ubushobozi bwo gucukura. Kongera PAC mu buryo amazi ayungururwa birema imiterere isa na gel ikora nk'akayunguruzo ku nkuta z'iriba. Aka gafunguzo kagabanya uburyo amazi yinjira mu iriba, bigafasha mu kubungabunga ubuziranenge bw'aho amazi anyura no kugabanya ibyago byo kwangirika kw'ibyiciro.
PAC ikoreshwa kandi mu kunoza imiterere yo gukumira shale y'amazi yo gucukura. Guhagarika shale ni ubushobozi bw'amazi yo gucukura mu gukumira shale ikora neza kugira ngo idakomeza kuzura no kubyimba. Gukura amazi no kwaguka kw'amazi yo gucukura bishobora gutera ibibazo nko kudakomera kw'imiyoboro y'amazi, imiyoboro ifunga, no kubura inzira z'amazi. Kongera PAC mu mazi yo gucukura bitera imbogamizi hagati y'amazi yo gucukura n'amazi yo gucukura. Iyi nzitizi ifasha mu kubungabunga ubusugire bw'urukuta rw'iriba mu kugabanya amazi no kubyimba kw'amazi yo gucukura.
Indi mikoreshereze ya PAC mu gucukura peteroli ni nk'inyongeramusaruro igabanya igihombo cy'amazi. Igihombo cyo kuyungurura bivuze igihombo cy'amazi yo gucukura yinjira mu gice cy'amazi mu gihe cyo gucukura. Iki gihombo gishobora kwangiza imiterere y'amazi, kubura imikorere y'amazi no kugabanya imikorere myiza yo gucukura. Gukoresha PAC bifasha kugabanya igihombo cy'amazi binyuze mu gukora agace k'urufunguzo ku nkuta z'amazi kabuza amazi kwinjira mu gice cy'amazi. Igihombo gito cy'amazi gifasha kugumana ubuziranenge bw'amazi no kunoza imikorere myiza yo gucukura.
PAC ishobora kandi gukoreshwa mu kunoza uburyo amazi yo gucukura agumana ubuziranenge. Guhagarara kw'amazi yo gucukura bivuga ubushobozi bw'amazi yo gucukura kugira ngo agumane ubuziranenge mu gihe cyo gucukura. Gukoresha PAC bifasha mu gutuza urukuta rw'iriba binyuze mu gukora agace k'urufunguzo ku rukuta rw'iriba. Aka gace k'urufunguzo kagabanya kwinjira kw'amazi mu rukuta kandi kagabanye ibyago byo kudahagarara kw'amazi yo gucukura.
Gukoresha selulose ya polyanionic mu gucukura peteroli bitanga inyungu nyinshi. PAC ikoreshwa mu kugenzura ubukana n'imikorere yo kuyungurura amazi yo gucukura, kunoza imikorere yo gukumira shale, kugabanya gutakaza ubushobozi bwo kuyungurura, no kunoza uburyo amazi yo gucukura ahagaze neza. Gukoresha PAC mu gucukura peteroli bifasha kongera imikorere no kugabanya ibyago byo kwangirika kw'imiterere y'amazi, kubura uruziga rw'amazi no kudahindagurika kw'amazi yo gucukura. Kubwibyo, gukoresha PAC ni ingenzi kugira ngo gucukura peteroli no kuyitunganya bigere ku ntego.
