Base on literatures researches about applications of MEOR nowadays and consideration of the oxygenic character of reservoir, the paper applied two kinds of reservoirs to screen nutrient systems for gas-producing microorganisms, and studied biogas production ability and metabolic mechanisms in porous medium in order to understand the mechanism of MEOR further.
The paper firstly showed that nutrient systems selected could stimulate biogases production by gas-producing microorganisms; the composition of bi...
