| titleOfInvention | CO prevention device for tight oil reservoir2Gas channeling responsive interpenetrating network gel particles and preparation method thereof |
| abstract | The invention discloses CO 2 Responsive interpenetrating network gel particles, the gel particles being prepared from the following materials in mass ratio: 15-25% of acrylamide monomer and 0-5% of temperature-resistant and salt-resistant monomer; 3 to 6 percent of CO 2 A responsive monomer; and a crosslinking agent, an initiator I, an initiator II and water. Preparing gel particles from acrylamide and a temperature-resistant and salt-resistant monomer, and mixing the prepared gel particles with CO 2 And (3) dissolving the response monomer and the gel particles in water and reacting for a period of time. In the present invention, the interpenetrating network structure increases the crosslinking density in the unit volume of the particles, thereby increasing the strength of the particles; CO of the invention 2 Responsive interpenetrating network gel particles with CO 2 After contact, the particles increase in size, indicating CO 2 Responsiveness to increase CO 2 Regulating strength during displacement while not reacting with CO 2 When contacted, the particles become smaller in size, and good reversibility is exhibited. |
