摘要
通过微观仿真模型驱油实验,研究了微生物对不同直径盲端内剩余油的驱替作用,比较了微生物、气体和聚合物对水驱后盲端类剩余油的不同作用效果。研究结果表明,微生物产生的生物气能够进入盲端,置换出水、气和聚合物溶液不能驱替出的盲端内剩余油。微生物驱具有独特的驱替出盲端类剩余油的优势。
The effects of microorganism on remaining oil at dead-end with different diameter were studied by oil displacement experiments on realistic micro-model. The effect of the microorganism,gas and polymers on the remaining oil at dead-end after waterflood-ing was compared. The results show that the biogas produced by the microorganism could enter the dead-end and replace the re-maining oil there,which could not be replaced by the gas,water and polymer solution. Microbial flooding has unique advantage of replacing the remaining oil at dead-end.
