COMPOUND FOR DRIVING OIL Russian patent published in 1994 - IPC

FIELD: oil industry. SUBSTANCE: there is well-known compound prepared on the basis of water solution of polymer of acrylamide including nonionic surface-active substance for improvement of rheological characteristics of the compound. Nonionic substance included in compound is water-soluble neonol АФ₉-12 or its commercial form and oil-soluble neonol АФ₉-6 taken in the following proportion ( mass/per cent): polyacrylamide - 0.03-0.2; water-soluble neonol АФ₃-12 or its commercial form in terms of neonol - 0.05-5.0; soluble neonol АФ₉-6 -0.05-5.0; water - 89.80-99.87. Stabilized compounds posses high rheological characteristics during filtration. Oil-soluble neonol favorably influences oil driving due to formation of stable dispersions and improvement of solubilization on interface of phases water-oil-rock. EFFECT: enhanced operating reliability. 2 tbl
