Abstract

Abstract: Based on similar principle of physical simulation experiment, we carried on a series of experiments of microorganism growth and migration in porous medium, enhanced oil recovery by microorganism, influence of different metabolic products and multiplex bacterium on oil recovery. Results indicate that multiplex bacterium N80 can grow and migrate in porous medium.
The effect of its different metabolic products on oil recovery will increase with the increase of metabolic products concentration.The contribution of surfactant to enhancement of oil recovery is primary, then the acid and the gas produced by metabolism.We also found that algebra sum of the oil displacement efficiency of the single metabolic product is less than that of common effect of all kinds of components, which show that cooperating effect of microorganism metabolic products redound to enhancement of oil recovery.

Key words: porous medium, microorganism, recovery, metabolic product, oil displacement
