METHOD OF INVESTIGATION OF COAGULATION OF SURFACE PROPERTIES OF POROUS MEDIUM FOR EXPULSION OF OIL

摘要

FIELD: oil production. SUBSTANCE: model of porous medium is treated with compositions of water-soluble salts of metals of I and II groups, aluminium and metals of transition valency with their content in water solution, g/l: 8.0-110.0 of water-soluble salts of metals of I and II groups and 0.01-0.4 of water-soluble salts of aluminium and metals of transition valency. After this model is saturated with oil which is expelled with water. EFFECT: improved accuracy reduced cost of investigation. 3 dwg, 4 tbl
