| titleOfInvention | Amphiphilic polymer super heavy oil viscosity reducer modified by siloxane quaternary ammonium salt and its preparation method and application |
| abstract | The invention provides a siloxane quaternary ammonium salt modified amphiphilic polymer super heavy oil viscosity reducer as well as its preparation method and application. The invention firstly synthesizes two double-bond-containing siloxane-based quaternary ammonium salt monomers with different structural features, and then carries out radical solution polymerization with cationic monomers and acrylamide respectively to obtain a viscosity reducer. The viscosity reducer of the present invention has a good viscosity reduction effect and temperature and salt resistance performance for super heavy oil, and also has excellent viscosity reduction effect for high salinity super heavy oil; Easy to demulsify and dehydrate. The synthesis process of the method of the invention is simple and easy to control, and the obtained viscosity reducer can be used alone without being compounded with other additives, and has excellent comprehensive performance and is environmentally friendly. |
