Technical Analysis of Enhanced Oil Recovery by Polymer Flooding
The Geological Research Institute of the Tenth Oil Production Plant of Daqing Oilfield Co., Ltd., Daqing, Heilongjiang, 163001 China
Polymer flooding is one of the effective technologies to improve oil recovery. This paper briefly introduces the mechanism of polymer flooding, and describes the application advantages of polymer flooding in heavy oil sandstone reservoirs in China. Combined with the application practice of polymer flooding EOR technology, the scheme of polymer flooding EOR technology is further explored from the aspects of polymer flooding oil supply, polymer flooding oil injection mode and polymer solution mass concentration, hoping to provide some references for the improvement of reservoir recovery.
Key words: Polymer flooding / recovery factor / high-viscosity crude oil
