FIELD: oil and gas production. SUBSTANCE: composition contains 0.1-15% of multifunctional organosilicon compound and 85-99.9% organic solvent. According to invention, organic solvent utilized is selected from petroleum products, alcohols, glycols and ethers, and organosilicon compound is selected from orthosilicic acid esters, oligoorganoethoxy(chloro)siloxanes, oligoorganohydridosiloxanes, polyorganosiloxanes, and their mixtures. Composition is injected into the formation. EFFECT: leveled profile of injection well injectivity, redistributed filtration streams in formation bulk, increased coverage of formation by watering and/or isolated inflow of formation water into wells. 3 cl, 3 ex
