| titleOfInvention | A kind of degreaser for salt-tolerant polymer flooding produced water and preparation method thereof |
| abstract | The invention belongs to the technical field of oilfield sewage treatment, and in particular relates to a degreaser for flooding produced water with a salt-tolerant polymer. The degreaser is composed of Gemini surfactant, montmorillonite, sodium dioctyl succinate sulfonate and water. Among them, Gemini surfactant is a symmetrical molecule with long carbon chain alkyl group and bisbenzene sulfonate polar group. The degreasing agent of the invention has the characteristics of simple preparation process, low cost, good salt resistance, salinity resistance up to 250,000 mg/L, and good degreasing effect, and the degreasing rate of polymer flooding produced water reaches more than 97%. Compared with the existing medicine, it is more than 50% higher. Therefore, the present invention can be widely used in the oil removal process of polymer flooding produced water. |
