| titleOfInvention | High-molecular surfactant type thick oil viscosity reducer and preparation method thereof |
| abstract | The invention discloses a high-molecular surfactant type thick oil viscosity reducer and a preparation method thereof, and mainly solves the problem that the viscosity reducing effect of the conventional thick oil viscosity reducer is poor. The preparation method comprises the steps of firstly reacting maleic anhydride with nonylphenol polyoxyethylene ether to obtain an intermediate product, and then reacting the intermediate product with a certain amount of acrylamide to prepare the high-molecular surfactant. The surfactant has the advantages of reliable preparation process, low cost, low use concentration and capability of remarkably reducing the viscosity of the thickened oil. |
