| titleOfInvention | Composition of surface-active agents, method of its production and application |
| abstract | FIELD: oil and gas industry. n SUBSTANCE: invention relates to the production and use of a surfactant composition in a tertiary oil recovery process. Surfactant composition for increasing oil recovery comprises a cationic nonionic surface-active agent – CSAA and an anionic surface-active agent – ASAA of the formulas given. Composition is obtained by mixing said surfactants at a molar ratio of 1:0.01–100. Fluid injection composition comprises the above composition or composition obtained by the above method. Method of producing a composition of a fluid injected into a formation for a tertiary oil recovery comprises mixing the above surfactant composition or obtained in the above manner with at least water, wherein the composition is 0.001 % to 10 % by weight of the injected liquid composition for tertiary oil recovery. Tertiary oil recovery method includes the step of performing a tertiary oil recovery in the presence of the above composition or composition obtained by the above process. Invention is developed in dependent items of the formula. n EFFECT: increased activity at the interface and stability, along with increased efficiency of oil displacement and the possibility of oil washing. n 9 cl, 10 tbl, 17 ex |
