| titleOfInvention | A kind of self-breaking heavy oil viscosity reducer and its preparation method and application |
| abstract | The invention relates to a self-demulsification heavy oil viscosity reducer and a preparation method and application thereof. The invention uses acrylamide, sodium p-styrene sulfonate and octadecyl acrylate as main raw materials to prepare the viscosity reducer from demulsification and heavy oil. The raw materials selected in the present invention have low cost and can be prepared by adopting a simple and traditional preparation process. At the same time, the obtained product has a high yield and has great advantages in the production process of the product. At the same time, the self-demulsification heavy oil viscosity reducer of the present invention has excellent viscosity-reducing ability for heavy oil, good temperature and salt resistance, and more prominent viscosity-reducing effect on super-heavy oil. The viscosity reducer has both self-demulsification properties, which can achieve the integration of viscosity reduction and demulsification, and achieve high-efficiency oil recovery. |
