Embodiment 1
[0073] A multifunctional reservoir reconstruction fluid, prepared by the following steps:
[0074] (A) First synthesize the thickener for reservoir stimulation fluid
[0075] Add bisacrylamide, vinylpyrrolidone, cationic unsaturated monomer, anionic unsaturated monomer and water into the reaction kettle and mix evenly, add caustic soda to adjust the pH value of the system to 9, add emulsifier and co-solvent, and pass nitrogen for two hours , add an initiator, react at a reaction temperature of 40°C for 5 hours, hydrolyze at 85°C for 8 hours to obtain a colloidal product, granulate, dry, and pulverize the colloid to obtain a thickener for reservoir reconstruction fluid;
[0076] In the above reaction system, taking the total reaction system mass as 100%, diacrylic acid accounts for 22.5% of the total mass, vinylpyrrolidone accounts for 6% of the total mass, dodecyldimethyldiallyl ammonium chloride accounts for 4% of the total mass, vinyl sulfonic acid sodium salt accounts for ...
