FIELD: oil production industry, particularly to develop oil and gas condensate deposits with the use of chemical reagents and to isolate permeable formations made up of terrigenous reservoirs with pore heterogeneity.
SUBSTANCE: method involves injecting gel-forming composition in watered formation, wherein the gel-forming composition comprises katamin AB used as gel formation rate regulator and taken in amount of 0.05-0.1 % by weight, ceolite component used in synthetic detergent production and taken in amount of 7.00-10.00% by weight, hydrochloric acid in amount of 7.00-12.00% by weight, remainder is water. Above composition is held in formation for time period necessary for gel formation, namely for 0.5-3 days and then water is injected in formation via injection well.
EFFECT: increased technological efficiency and oil and gas condensate deposit development efficiency due to gel-forming time regulation.
