litaba

Litabeng tsa morao tjena tsa indasteri, polyacrylamide, motsoako oa polymer o feto-fetohang, e hlahile e le moetapele 'marakeng oa lik'hemik'hale tsa oli. Litšebeliso tsa eona tse fapaneng, ho kenyeletsoa le ho hlaphoheloa ha oli ho ntlafalitsoeng (EOR), maro a ho cheka le kalafo ea metsi, li hohetse tlhokomelo e kholo ho tsoa ho libapali tse kholo indastering ea oli le khase.

Polyacrylamide ke polymer e qhibilihang ka metsing e ka hlahisoang ka mefuta e fapaneng mme e ka etsoa ho latela litlhoko tse itseng tsa oli. Ha mesebetsi ea ho cheka e ntse e tsoela pele ho atoloha lefatšeng ka bophara, tlhoko ea litharollo tse sebetsang le tse tsitsitseng tsa ho eketsa ho ntšoa ha oli e se e le ea bohlokoa haholo. Polyacrylamide, ka thepa ea eona e ikhethang, e bontšitse bokhoni bo boholo ba ho tobana le liphephetso tsena.

E 'ngoe ea lits'ebetso tse ka sehloohong tsa polyacrylamide ke ho hlaphoheloa ha oli ka mokhoa o ntlafalitsoeng (EOR). Theknoloji ena e etselitsoe ho eketsa tlhahiso ea oli ho tsoa polokelong ka ho kenya metsi kapa lik'hemik'hale ho tlosa le ho tlosa oli e setseng. Jwalo ka karolo ea bohlokoa ea metsoako ea ho falla ha oli e thehiloeng metsing, polyacrylamide e ka ntlafatsa katleho ea ho falla ha oli le ho eketsa ho hlaphoheloa ha oli.

Ho phaella moo, polyacrylamide e sebediswa haholo ho tjheke maro e le sesebelisoa sa ho tiisa le ho fetola rheology. E ntlafatsa bokgoni ba mokelikeli ba ho jara dikotwana ho ya hodima metsi le ho boloka botsitso ba kgatello, ho netefatsa tshebetso e sebetsang hantle ya ho tjheke. Tlhokeho ya maro a tjheke a tsoetseng pele a nang le polyacrylamide e lebelletswe ho eketseha ha indasteri ya oli e ntse e sutumelletsa mekgwa e rarahaneng ya ho tjhekella.

Sebaka se seng seo polyacrylamide e bapalang karolo ea bohlokoa ho sona ke kalafong ea metsi bakeng sa ts'ebetso ea oli le khase. Ha khaello ea metsi e ntse e fetoha bothata ba lefats'e ka bophara, lik'hamphani tsa oli le khase li ntse li tsepamisa maikutlo haholoanyane ho sebeliseng hape le ho sebelisa metsi a litšila hape. Polyacrylamide e thusa ts'ebetsong ea kalafo ea metsi, e tlosa litšila, lintho tse tiileng tse emisitsoeng le litšila ka katleho, e leng se etsang hore metsi a lokele ho sebelisoa hape kapa ho ntšoa ka mokhoa o sireletsehileng.

Leha ho le jwalo, ditaba tsa botsitso le tsa tikoloho di ntse di le bohlokwa. Ho ntse ho etswa boiteko ba ho fokotsa ditlamorao tsa tikoloho tse amanang le tlhahiso le tshebediso ya polyacrylamide. Bafuputsi ba ntse ba hlahloba mekgwa e meng e sireletsang tikoloho, mekgwa e ntlafetseng ya ho sebedisa polymer hape, le mahlale a matjha a ho fokotsa ditshila tsa dikhemikhale.

Indasteri ea oli le khase e ntse e hatela pele ho ea bokamosong bo sebetsang hantle le bo tsitsitseng, 'me polyacrylamide e lebelletsoe ho bapala karolo ea bohlokoa phetohong ena. Ka mefuta e mengata ea lits'ebetso tsa eona le lintlafatso tse ka bang teng nts'etsopele ea lihlahisoa, motsoako ona o sebetsang ka bongata o na le tšepiso ea ho ntlafatsa ho hlaphoheloa ha oli, ts'ebetso ea ho cheka le lits'ebetso tsa kalafo ea metsi tse sireletsang tikoloho.
