FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil and gas industry, particularly to compositions for control of development of oil deposits, including alignment of injectivity profile of injection wells. Composition for increasing oil production, containing polymer agent, cross-linking agent and water, as polymer reagent contains grade A reagent AC-CSE-1313, as crosslinking agent is hydrochloric acid or CSE-0713 reagent and additionally ammonium fluoride in following proportions, wt%: grade A AC-CSE-1313 is 3.0-6.0, hydrochloric acid (per HCl) or CSE-0713 reagent (per HCl) is 3.0-8.0, ammonium fluoride is 0.1-1.0, mineralised water is rest.
EFFECT: technical result is increase of efficiency, expansion of resources.
