[0046] In yet another specific embodiment of the present invention, a method for preparing the above-mentioned temperature-resistant heavy oil viscosity-reducing polymer is provided, including:
[0047] (1) Under an inert atmosphere, sequentially add acrylamide monomer, sodium acrylate monomer, hydrophobic monomer, and temperature-resistant functional monomer into water, and stir until clear to obtain solution I;
[0048] (2) Continue to add micro-crosslinking monomer and temperature stabilizer to solution I, stir until all dissolve to obtain solution II;
[0049] (3) Add the initiator into the solution II after heating up, stir, stop stirring when the solution becomes viscous, remove the inert atmosphere, and seal the reaction.
[0050] In yet another specific embodiment of the present invention, in step (1), the inert atmosphere is nitrogen;
[0051] In yet another specific embodiment of the present invention, in step (3), the heating temperature is controlled to be 50-70°C...
