| titleOfInvention | Surfactant, preparation method thereof and application of surfactant in fracturing oil displacement process |
| abstract | The invention relates to a surfactant, which has a molecular formula as follows: the invention also provides application of the surfactant in fracturing oil displacement. The surfactant has the characteristics of reproducibility, easy biodegradation and no toxicity, and 10 percent of the surfactant is formed between an aqueous solution fracturing system with the product concentration of more than 0.05 percent and crude oil ‑3 The ultra-low interfacial tension of mN/m belongs to an environment-friendly surfactant, the oil washing efficiency is high, the oil washing rate reaches more than 80%, and the fracturing process can be injected into the stratum to fully play the dual functions of fracturing and oil displacement and further improve the crude oil recovery ratio. |
