Abstract CO2 flooding has been widely studied and applied to improve oil recovery from low
permeability reservoirs. Both the experimental results and the oilfield production data indicate
that produced oil components (POC) will vary during CO2 flooding in low permeability
reservoirs. However, the present researches fail to explain the variation reason and rule. In this
study, the physical model of the POC variation during CO2 flooding in low permeability
reservoir was established, and the variation reason and rule were defined. To verify the
correctness of the physical model, the interaction rule of the oil-CO2 system was studied by
related experiments. The… More >
