| titleOfInvention | A kind of two-phase viscosity modifier and preparation method thereof |
| abstract | The invention relates to the technical field of oilfield exploitation, in particular to a two-phase viscosity modifier and a preparation method thereof. The two-phase viscosity modifier is prepared by copolymerizing acrylamide, methoxyethyl acrylate and sodium p-styrenesulfonate. The two-phase viscosity modifier of the invention acts on the two phases of oil and water, can significantly increase the viscosity of the aqueous solution, and emulsifies the aqueous solution with the heavy oil to reduce the viscosity of the heavy oil. The two-phase viscosity modifier can greatly change the oil-water viscosity ratio in oil reservoir exploitation, improve the oil field development effect, and solve the problem that the existing heavy oil exploitation is difficult. |
