浅析微生物对提高原油采收率的作用

Roles of microorganisms playing in EOR improvement

微生物采油对油藏无二次污染,对环境和人体健康无潜在危害,是一种环保的原油开采工艺,微生物及其代谢产物可以间接影响原油采收率。关于微生物及其代谢产物对原油的作用,可从微生物作用前后原油组分的变化分析得到,从而更清晰地理解微生物采油作用原理。

Microbial oil recovery is environmental friendly and has no secondary pollution to oil reservoir.Microorganismsand their metabolites can indirectly affect efficiency of oil recovery(EOR).The effect of microorganisms and their metabolites oncrude oil can be obtained from the analysis of the composition of crude oil before and after microbial action,so as to understand theprinciple of microbial oil production more clearly.
