Status quo of EOR technology development based on flue gas flooding

International oil price spike and greenhouse gas reduction have a great impact on the development of flue gas flooding.This paper introduces the development,the merits and defects of gas displacement,and the emission of flue gas in China.It mainly discusses the EOR mechanism based on flue gas flooding,the flue gas processing technology and its application in domestic oilfields.Application results show that recovery of oil reservoirs,especially of heavy oil reservoirs,can be effectively enhanced based on flue gas flooding.
