Analysis on the variation law of polymer flooding index in the first and second oil reservoirs of Daqing Oilfield
Institute of Geology, No.6 Oil Production Plant of Daqing Oilfield Company, Zip code: 163000 China
With the development of oilfield exploitation in China, in-depth understanding of the change of polymer flooding injection-production index can effectively alleviate the contradiction of polymer flooding and improve the production efficiency. Based on this, taking Daqing oilfield as an example, this paper makes a detailed analysis on the classification of polymer flooding stages and the prediction methods of development indicators for the first and second oil layers, and mainly discusses the variation rules of injection-production indicators in the process of polymer flooding for the first and second oil layers, in order to provide reference for others.
Key words: Daqing Oilfield / Reservoir polymer / Flood injection-production index / Change rule
