摘要
本研究利用油田污水处理站和炼油厂的活性污泥来提高原油采收率。对活性污泥中微生物产气、产酸、乳化降解原油和LAZAR模型驱油等实验效果进行了综合评价,结果表明,活性污泥中各类微生物具有较强的乳化能力,微生物代谢产物中气体、有机酸等活性组分可使原油采收率提高9．52%～21．88%,为今后深入研究活性污泥生物学特性和驱油机理提供了实验依据。
The activated sludge from waste water treatment plants in oilfields and oil refining factories was used to increase oil recovery.The characters of activated sludge was synthetically evaluated by producing gas and organic acid,effect of emulsifying and biodegrading crude oil and oil displacement efficiency in LAZAR physics model.The results showed that activated sludge increased oil recovery after water flooding up to 9.52%～21.88%.The base test was applied for researching biology character of activated sludge and oil displacement mechanism.
