| titleOfInvention | Temperature-resistant salt-resistant multi-copolymerization pre-crosslinked gel particles and preparation method and application thereof |
| abstract | The invention provides a temperature-resistant and salt-resistant multi-copolymerization pre-crosslinked gel particle, and a preparation method and application thereof, and belongs to the technical field of oil exploitation, transportation and chemical engineering. The pre-crosslinked gel particles provided by the invention are formed by copolymerizing acrylamide and 2-acrylamide-2-methylpropanesulfonic acid, the copolymer has a stable structure and good high-temperature aging resistance, is not easy to hydrolyze, has good compatibility with polymers, greatly improves the viscosity of the system, improves the suspension performance of the pre-crosslinked gel particles in the system, and enables the oil displacement capacity of the system to be stronger and the oil displacement efficiency to be higher. |
