Abstract

što se u podzemnu formaciju ubrizgava pod pritiskom od 0,1 kPa do 200 MPa, iznad atmosferskog pritiska kiseli rastvor temperature od o - 95 C, koji obuhvata 5 do 50 mas.% kiseline, 45 do 95 mas.% vode, i 0,01 do 5 mas.% u vodi rastvorljive smeše kopolimera A i B pri čemu smeša obuhvata 60 do 90 mas.% kopolimera A koji sadrži oko 50 mas.% najmanje jednog monomera iz grupe koju čine natrijum 2-akrilamido-2-metilpropan sulfonar ili 2- akrilamido-2-metilpropan sulfokiselina i oko 50 mas.% najmanje jednog monomera iz grupe koju čine akrilamid i metilakrilamid, i 10 do 40 mas.% kopolimera B koji sadrži oko 30 mas.% najmanje jednog monomera iz grupe akrilamida ili metakrilamida i oko 70 mas.% monomera najmanje jednog iz grupe koju čine natrijum 2-ak-rilamido-2-metilpropansulfonat ili 2-akrilamido -2-metilpropan sul-fokiselina, pri čemu se postupak provodi u vremenu od 1 časa do 500 dana.
