Beschreibung
Zusammenfassung:	FIELD: oil production industry. SUBSTANCE: compound is used for increasing oil output from nonuniform oil beds. Compound contains used alkali from wet processes of gas cleaning and also appropriate additive at following proportioning of components, mass%: used alkali 99-99.99, additive in term of dry matter 0.01-1. Introduced in function of additive are following selective water-soluble polymers of anionic type, cationic type or non-ionic type such as: polyacrylamide of various grade, hydrolyzed nitrile fibre, carboxymethylcellulose, and biopolymer. Application of aforesaid compound allows for increasing efficiency in adjustment of permeability of oil bed. Compound can be used at medium or late stages in development of oil deposits with mineralized water being injected. EFFECT: higher efficiency. 3 tbl
