| titleOfInvention | High-viscosity system for fluidity control of reservoir in strongly water-flooded zone and its preparation method and application |
| abstract | The invention discloses a high-viscosity system for regulating the fluidity of an oil reservoir in a strongly water-flooded zone, which, in parts by mass, comprises: 0.1-0.8 parts of high molecular polymer A; 0.1-0.3 parts of stabilizer; 0.01-0.05 parts of complex Mixture; 90 to 150 parts of water. A preparation method of a high-viscosity system for fluidity control of a highly water-flooded zone oil reservoir, comprising the following steps: (1), adding a formula amount of water into a container, and while stirring, slowly adding a formula amount of polymer polymer to the edge of the water vortex Compound A, continue to stir for more than 2 hours until polymer A is completely dissolved to obtain solution B; (2), seal the solution B obtained in step (1) at RT ~ 85 ℃ and let stand for 24 ~ 48 hours, and then talk about the formula amount of stabilizer , and complexing agent are added to solution B in turn, and after stirring evenly, a high viscosity system for fluidity control of reservoirs in strong water-flooded zone is obtained. The invention also discloses the use of the above high-viscosity system as a plugging agent for oil reservoirs in strong water-flood zones. |
