Application of polymer flooding technology in Daqing Oilfield

Demin Wang

Abstract

According to the results of the research in the laboratory and field tests, the experiences of polymer flooding in Daqing Oilfield in seven years are analyzed. The actual recovery in the field and the major factors influencing recovery efficiency are investigated. The methods for enhancing recovery efficiency, the measures to obtain a uniform polymer flooding front and ways to lower the costs for producing crude oil by polymer flooding are discussed. The effectiveness of polymer flooding technology applied in Daqing Oilfield can provide some references for further application of polymer flooding in China.
