| Abstract: | Low permeability reservoir has the characteristics of low porosity,low permeability,low natural output,and injecting and producing nothing.According to developing difficulties of almost low permeability oil field,with a bulk of CO2 gas sources are discovered,injecting CO2 to displace oil in low permeability oil reservoir becomes a kind of EOR(enhanced oil recovery) method.The paper discusses the oil displacement mechanism and adaptability of injecting CO2 EOR technology. |

| Keywords: | low-permeability injecting CO2 mechanism enhanced oil recovery |
