| titleOfInvention | Composition for recovering oil from formation |
| abstract | The invention relates to advanced industry and is intended to enhance oil recovery by reservoir flooding in primary and secondary formation methods. The goal is to increase the oil-driving ability of the composition, to improve the technological effectiveness of its use. For this, the composition contains the following components in their ratio, wt.X: oxyethylated alkylphenol, for example SP-10, or neonol AF 9-12, or exceeded 2.0-25.0; the anti-active surfactant is 1.0 - 17.0; ammonium salt 15.0-32.0, rhodium potassium or sodium, or ammonium O, 1-0.5, and ammonia water the rest. As an aioactive surfactant, the composition contains an alkyl aryl sulfonate or alkane sulfonate. The composition is obtained by dissolving its components in water and is used to displace oil from a field. The coefficient of oil displacement increases by 3-13Z, and the injection volume decreases by a factor of 3-10. The composition can be used to increase the worsening of the worms with a temperature greater than 70 ° C, and the freezing temperature can be lowered to minus A6 - minus 52 ° C, which makes it possible to use it in winter, I zp f-ly, 1 taOL. g (L |
