| In recent years, polymer flooding became the main measures to improve oil recovery. However, as the polymer injection prolonged, caused the polymer injection Wells plug serious problem .This paper Sa Dong region geography properties, diversity of core test by simulating, the formation mechanism of polymer injection Wells plug.Through a lot of indoor test and simulation experiment, formation core developed a reversing agents with the antioxidant wetting agents to solve the main wall type CYX-1 polymer injection Wells solution plugging agent.The result of this paper for the mining of polymer injection Wells is very important significance. Meanwhile to enhance recovery rate also have important significance. |
