| titleOfInvention | Improved betaine surfactant composition system and application thereof |
| abstract | The invention discloses an improved betaine surfactant composition system and an application thereof. The system comprises betaine surfactants and oil well injected water, wherein the betaine surfactants are selected from more than any two types of alkyl dimethyl betaine, alkyl amido propyl dimethyl betaine, alkyl sulpho betaine and alkyl hydroxyl sulpho betaine; and in the system, the total concentration range of all the surfactants in terms of 100% of activity is 0.005-1%. The betaine surfactant composition system provided by the invention has strong capacity of resisting the degree of mineralization, good matching with polymers particular PAM (polyacrylamide) type polymers and high temperature stability, is used for three times of chemical displacement of reservoir oil to ensure that 10-15% more of oil reservoirs can be exploited, and is low in using concentration, so that the cost is greatly reduced; and moreover, the betaine surfactant composition system does not contain alkali, so that the selection of polymers is wider, and the significance for protecting natural resources is also very important. |
