METHOD OF DEVELOPING OIL RESERVOIR

摘要

FIELD: oil industry.SUBSTANCE: invention relates to oil industry, in particular, to methods of development of oil reservoir by polymer water flooding. Method of development of oil formation, which involves pumping to formation of fringe of water solution of partially hydrolyzed polyacrylamide-PAA, said solution additionally contains wood saponified resin-CDR in the following proportions, wt%: PAA 0.03 -0.15, CDR -0.005 0.001, water mineralization to 240 g/dmrest.EFFECT: technical result is high efficiency of processing.1 cl, 1 tbl
