Abstract RU 2136868 C1

FIELD: oil and gas production. SUBSTANCE: geological field investigations of wells are preliminarily performed, after which aqueous solution of anionic surfactant-"Polyglycerine" mixture is injected in sectors with value of porous medium permeability higher than 0.11 sq.mcm, injecting wells having been preliminarily injected with aqueous solution of calcium chloride and cationic compound. EFFECT: increased efficiency of developing oil deposit due to increased displacement coefficient and increased coverage of formation with treatment fluid. 2 dwg, 1 tbl
