| titleOfInvention | High-molecular thick oil emulsifying viscosity reducer and preparation method and application thereof |
| abstract | The invention provides a high-molecular thick oil emulsifying viscosity reducer and a preparation method and application thereof, wherein the high-molecular thick oil emulsifying viscosity reducer comprises the following components: acrylamide, a sulfobetaine monomer and an itaconic acid double-long-chain ester monomer; the mol ratio of the acrylamide monomer, the sulfobetaine monomer and the itaconic acid double-long-chain ester monomer is 65-70: 30-45: 1-5. The high-molecular thick oil emulsifying viscosity reducer disclosed by the invention contains a quaternary ammonium type cation structure, so that the foaming capacity is stronger, thick oil can be effectively emulsified, the preparation method is simple and easy to control, byproducts are less, and the problems of poor viscosity reducing effect, poor temperature resistance and salt resistance, poor emulsifying effect and the like are effectively solved. |
