Ingxenye ye-Hydrolytic Polyacrylamide Anion (PHPA) esetshenziselwa ukuhambisa uwoyela ukuze kutholakale uwoyela wezinga eliphezulu.Kuyimpahla yodaka yokumba esebenza kahle.Ivamise ukusetshenziselwa ukumba, ukwelashwa kwamanzi angcolile ezimbonini, ukwelashwa kodaka lwe-inorganic kanye nemboni yephepha.

I-Polyacrylamide iwuhlobo lwe-ejenti yokwelashwa kwamakhemikhali e-oilfield enemisebenzi eminingi, esetshenziswa kabanzi ukubhola, ukufaka usimende, ukuqeda, ukusebenza, ukuqhekeka, ukwenza i-asidi, umjovo wamanzi, ukulawulwa kwephrofayili yokuxhuma amanzi kanye nokukhiqizwa kukawoyela wezinga eliphezulu, ikakhulukazi ekubholeni, ukulawula iphrofayili yokuxhuma amanzi. kanye nokukhiqizwa kukawoyela emazingeni aphezulu.Isixazululo se-polyacrylamide sine-viscosity ephezulu, ukuqina okuhle, ukugeleza kwe-flocculation kanye nokulawulwa kwe-rheological, futhi isetshenziswa njenge-ejenti yokususa uwoyela kanye nesilawuli sodaka sokumba ekuxhashazweni kwamafutha.Esigabeni esimaphakathi nesemuva sokuxhashazwa kukawoyela, izikhukhula ze-polymer kanye nobuchwepheshe bezikhukhula ze-asp busetshenziswa kabanzi e-China ukuthuthukisa ukutholakala kukawoyela.Isilinganiso sejubane likawoyela-amanzi sathuthukiswa ngokujova isixazululo se-polyacrylamide, futhi okuqukethwe kwamafutha angcolile ezintweni ezikhiqizwayo kwanda.Ukwengezwa kwe-polyacrylamide ekubuyiseleni uwoyela esikhungweni semfundo ephakeme kungakhuphula umthamo wokususwa kukawoyela, kugweme ukuwohloka kongqimba lukawoyela, futhi kuthuthukise ukusebenza kahle kombhede kawoyela.Imboni ye-petroleum yaseChina ingumsebenzisi omkhulu we-polyacrylamide.Inqubekelaphambili yesayensi nezobuchwepheshe ye-polyacrylamide ikhuthaza ukuthuthukiswa kwemboni ye-petroleum yaseChina, futhi isidingo semboni ye-petroleum sisheshisa ijubane lokuqanjwa kwesayensi nezobuchwepheshe kwe-polyacrylamide kanye nokuthuthukiswa kwembonini.

Ukuhlanza amanzi kuhlanganisa ukuhlanzwa kwamanzi aluhlaza, ukukhucululwa kwendle kanye nokuhlanza amanzi ezimbonini.Ingasetshenziswa kanye nekhabhoni ecushiwe ekwelapheni amanzi aluhlaza ukufingqa nokucacisa izinhlayiya ezimisiwe emanzini aphilayo.Uma i-organic flocculant acrylamide isetshenziselwa ukufaka esikhundleni se-flocculant ye-inorganic, umthamo wokuhlanza amanzi ungakhuphuka ngaphezu kuka-20% ngisho noma ithangi le-sedimentation lingashintshiwe.Ekulapheni indle, i-polyacrylamide ingakhuphula izinga lokusetshenziswa kokugaywa kabusha kwamanzi futhi ingasetshenziselwa ukuqeda amanzi ngodaka.Isetshenziswa njengokwakhiwa okubalulekile ekuhlanzeni amanzi ezimbonini.
