| titleOfInvention | Gemini polyoxyethylene ether succinate surfactant for oil displacement and preparation method thereof |
| abstract | The invention relates to a Gemini polyoxyethylene ether succinate surfactant for oil displacement and a preparation method thereof. According to the method, the Gemini alkylphenol polyoxyethylene ether sulfosuccinate which is salt-resistant, temperature-resistant and high in wettability is obtained by synthesizing the Gemini alkylphenol polyoxyethylene ether sulfosuccinate, and the Gemini alkylphenol polyoxyethylene ether sulfosuccinate is particularly suitable for high-temperature and high-salt oil reservoirs. The Gemini alkylphenol polyoxyethylene ether sulfosuccinate type temperature-resistant salt-tolerant ultralow interfacial tension surfactant has a good popularization and application prospect and good social and economic benefits. |
