Partial Hydrolytic Polyacrylamide Anion (PHPA) ku oil displacement wothandizira kuti abwezeretse mafuta apamwamba.Ndiwobowola matope ndi ntchito yabwino.Nthawi zambiri amagwiritsidwa ntchito pobowola, kuyeretsa madzi otayira m'mafakitale, mankhwala a sludge komanso makampani opanga mapepala.

Polyacrylamide ndi mtundu wa Mipikisano zinchito oilfield mankhwala wothandizila mankhwala, amene chimagwiritsidwa ntchito pobowola, simenti, akamaliza, workover, fracturing, acidizing, jekeseni madzi, madzi plugging mbiri kulamulira ndi apamwamba mafuta kupanga, makamaka pobowola, madzi plugging mbiri ulamuliro. ndi kupanga mafuta apamwamba.Njira yothetsera polyacrylamide imakhala ndi kukhuthala kwakukulu, kukhuthala bwino, kuyandama komanso kuwongolera bwino, ndipo imagwiritsidwa ntchito ngati chowongolera mafuta ndikubowola matope pakugwiritsa ntchito mafuta.Pakatikati komanso mochedwa kugwiritsa ntchito mafuta, kusefukira kwa ma polima komanso matekinoloje osefukira a asp amagwiritsidwa ntchito kwambiri ku China kuti athandizire kubwezeretsa mafuta.The mafuta-madzi liwiro chiŵerengero anali bwino ndi jekeseni polyacrylamide njira, ndi zili mafuta yaiwisi mu zinthu opangidwa chinawonjezeka.Kuphatikizika kwa polyacrylamide pakuchira kwamafuta apamwamba kumatha kukulitsa kusuntha kwamafuta, kupewa kuwonongeka kwa mafuta osanjikiza, ndikuwongolera kuchira kwa bedi lamafuta.Makampani amafuta aku China ndi omwe amagwiritsa ntchito kwambiri polyacrylamide.The sayansi ndi luso patsogolo Polyacrylamide amalimbikitsa chitukuko cha mafakitale China mafuta, ndi kufunika kwa makampani mafuta Iyamba Kuthamanga mayendedwe a sayansi ndi luso luso la Polyacrylamide ndi chitukuko cha makampani.

Kuyeretsa madzi kumaphatikizapo kuyeretsa madzi osaphika, kuyeretsa zimbudzi ndi kuyeretsa madzi m'mafakitale.Itha kugwiritsidwa ntchito limodzi ndi adamulowetsa mpweya mu madzi yaiwisi mankhwala condense ndi kumveketsa inaimitsidwa particles m'madzi amoyo.Ngati organic flocculant acrylamide ntchito m'malo flocculant zachilengedwe, madzi kuyeretsa mphamvu akhoza ziwonjezeke ndi oposa 20% ngakhale thanki sedimentation si kusinthidwa.Pochiza zimbudzi, polyacrylamide imatha kuonjezera kuchuluka kwa magwiritsidwe ntchito obwezeretsanso madzi ndipo itha kugwiritsidwanso ntchito pochotsa madzi m'thupi la sludge.Ntchito ngati chiphunzitso chofunika mafakitale mankhwala madzi.
