Munhau dzechangobva kuitika muindasitiri, polyacrylamide, musanganiswa wepolymer unoshandiswa zvakasiyana-siyana, wave kutungamira mumusika wemakemikari emumunda wemafuta. Mashandisirwo ayo akasiyana-siyana, anosanganisira kudzoreredza mafuta zvakanyanya (EOR), mvura yekuchera uye kurapwa kwemvura, zvakakwezva kutariswa kukuru kubva kune vatambi vakuru muindasitiri yemafuta negesi.
Polyacrylamide ipolymer inonyungudika mumvura inogona kugadzirwa mumhando dzakasiyana-siyana uye inogona kugadziriswa zvichienderana nezvinodiwa munzvimbo yemafuta. Sezvo mabasa ekuchera achiramba achiwedzera pasi rose, kudiwa kwemhinduro dzinoshanda uye dzinogara kwenguva refu dzekuwedzera kuburitswa kwemafuta kwave kwakakosha. Polyacrylamide, ine hunhu hwayo hwakasiyana, yakaratidza kugona kukuru mukusangana nematambudziko aya.
Imwe yenzira huru yekushandisa polyacrylamide ndeyekuvandudza mafuta ekushandisa (EOR). Iyi tekinoroji yakagadzirirwa kuwedzera kugadzirwa kwemafuta kubva mudura nekubaya mvura kana makemikari kuti abvise mafuta asara. Sechinhu chakakosha chemafuta anoshandiswa mumvura, polyacrylamide inogona kuvandudza kushanda zvakanaka kwemafuta ekushandisa uye kuwedzera kudzoreredzwa kwemafuta.
Pamusoro pezvo, polyacrylamide inoshandiswa zvakanyanya mukuchera mvura semuchina wekugadzirisa tsinga uye rheology. Inosimudzira kugona kwemvura kutakura zvidimbu pamusoro uye kuchengetedza kumanikidzwa kwakaringana, zvichiita kuti kucherwa kushande zvakanaka. Kudiwa kwemvura yepamusoro ine polyacrylamide kunotarisirwa kuwedzera sezvo indasitiri yemafuta ichisimudzira matekiniki ekuchera akaomarara.
Imwe nzvimbo iyo polyacrylamide inoita basa guru ndeyekugadzirisa mvura yemafuta negasi. Sezvo kushomeka kwemvura kuri kutambudza pasi rose, makambani emafuta negasi ari kuramba achitarisa pakushandisazve mvura yakasviba. Polyacrylamide inobatsira mukurapa mvura, ichibvisa tsvina, zvinhu zvakanyungudutswa uye zvinosvibisa, zvichiita kuti mvura ive yakakodzera kushandiswazve kana kubudiswa zvakachengeteka.
Zvisinei, nyaya dzekuchengetedza nharaunda nedzezvakatipoteredza dzichiri kukosha. Kuedza kuri kuitwa kuderedza migumisiro yezvakatipoteredza inokonzerwa nekugadzirwa nekushandiswa kwepolyacrylamide. Vatsvaguriri vari kutsvaga dzimwe nzira dzisingakuvadzi nharaunda, nzira dzakavandudzwa dzekushandisa polymer patsva, uye matekinoroji matsva ekuderedza marara emakemikari.
Indasitiri yemafuta negesi iri kufambira mberi kuenda kune ramangwana rinoshanda uye rinogara kwenguva refu, uye polyacrylamide inotarisirwa kuita basa rakakosha mukuchinja uku. Nekushandiswa kwayo kwakasiyana-siyana uye kuvandudzwa kunogona kuitika mukugadzirwa kwechigadzirwa, iyi compound ine mabasa akawanda ine vimbiso yekuvandudza kudzoreredzwa kwemafuta, mashandiro ekuchera uye maitiro ekuchenesa mvura asingakuvadzi nharaunda.
