内源微生物驱油技术利用地层中已经存在的微生物群落，通过注水井向地层中注入适量的营养激活剂，从而激活油藏中有益微生物群落，利用其自身在油藏中的代谢活动及代谢产物与岩石、原油和水的界面相互作用，降低界面张力，改善原油的流动性质，提高原油采收率。%Endogenous microbial oil displacement technology is used with microbial existing in the reservoirs, inject adequate nutrition activator to them through injection wells, thus activate the beneficial microbial in reservoirs to reduce the interfacial tension, improve the flow properties of crude oil, and increase oil recovery efficiency by use of metabolic activities of microbial in the reservoir and interface interaction between metabolites and rock, crude oil and water.
