METHOD OF DEVELOPMENT OF WATER-FLOODED DEPOSIT WITH RESERVOIRS OF NON-UNIFORM PERMEABILITY

摘要

FIELD: oil and gas industry.;SUBSTANCE: method of development of water-flooded deposit with reservoirs of non-uniform permeability consists in pumping into reservoir water solution of hydroxychloride aluminium - waste of production of benzene alkylation with olefins - with successive pressurising of displacement agent, in introducing of oxyethylidendiphosphonic acid at amount of 0.025-0.1% into 15-30% water solution of hydroxychloride aluminium -waste of production of benzene alkylation with olefins.;EFFECT: upgraded efficiency of oil displacement due to formation of water insulating screen in water saturated - washed up zone of reservoir at considerable distance from bottom hole of well.;1 tbl, 10 ex
