| 摘 要： | 采用数值模拟方法对影响朝阳沟油田微生物驱油效果的各项因素进行分析发现：微生物浓度对微生物驱油效果具有一定的影响；一定的微生物浓度下，存在合理的微生物用量；而相同微生物用量条件下，多段塞式注入优于单一段塞式注入；在注微生物1a以后，再注入一段营养液，可以提高微生物的驱油效果。数值模拟表明，微生物驱6a后较水驱提高采收率1．73％，并使含水率降低，最大降幅可达14．32％。

| Abstract: | The influence factors of MEOR in Chaoyanggou oilfield are analyzed based on numerical simulation.The simulation shows that microbial concentration has a certain effect on MEOR;there is a rational microbial quantity under a particular microbial concentration,while multi-slug injection is better than single slug under the same microbial quantity.MEOR efficiency will be improved by injection nutritive solution after injecting microbial for one year.Numerical simulation shows that,comparing with water-flooding,MEOR has done a better job,enhancing oil recovery by 1.73% after 6 years and reducing water cut to as much as 14.32%. |
