The study of seepage laws during microbial enhanced oil recovery helps to elucidate the mechanisms behind flooding, and use large-scale physical simulation experimental devices can more objectively accurately investigate microbes in porous media, evaluate displacement efficiency systems. In this study, experiments flooding were conducted via a slab outcrop core, biochemical parameters such as concentration Bacillus subtilis, nutrient concentration, surface tension, pressure data tracked evaluated. analysis revealed that characteristics field change elucidates migration rules nutrients, well rule tension. results show after system is injected, cells nutrients are preferentially distributed near injection along main flow paths, with bacterial adsorption retention capacity being greater than those agents. Owing action microorganisms their metabolites, overall within model increased, From production well, decreases stepwise, high-pressure gradient zone mainly concentrated well. fermentation mixture subtilis increased by 0.73 MPa, reduced tension up 49.8%, rate 6.5%.
