| titleOfInvention | Double stimuli expanded gel particle and preparation method thereof for carbon dioxide drive process anti-gas channeling |
| abstract | The preparation method of double stimuli expanded gel particle of the present invention for carbon dioxide drive process anti-gas channeling: (1) by acrylamide monomer formation solution soluble in water; crosslinking agent, temperature-responsive monomer methacrylic acid N are added into acquired solution; N- dimethylaminoethyl monomer and photosynthesis-carbon dioxide response monomer [2- (methylacryloyl oxygroup) ethyl] dimethyl-(3- propyl sulfonic acid) ammonium hydroxide; it stirs evenly to form mixed monomer solution polymerization system, nitrogen is led to while stirring into polymerization system with the dissolved oxygen in removing system；Mixed monomer solution is mixed with initiator solution and carries out polymerization reaction.The present invention is obtained in CO 2 With under thermostimulation can prolonged expansion, and under acidic environment can reexpansion microgel particle, to play closure function for a long time. |
