摘要
对一种耐高温泡沫体系(COL-3)的驱油效率及影响因素进行了实验研究。结果表明,随着起泡剂浓度的增加,泡沫驱油效率逐渐增大,最后趋向平稳,且起泡剂最经济、有效的使用浓度为0.3%;起泡剂采用段塞注入,泡沫的驱油效率最大;随着渗透率极差的增大,泡沫驱油效率变小。
The oil displacement efficiency and its influence factors of a heat resistant foam system（COL-3） were researched. The results indicate that, with increasing concentration of foaming agent, displacement efficiency increases gradually and finally tends to stable. Meanwhile, optimal appropriate concentration of foaming agent is 0.3%. Results of different injection ways show that the slug injection is the optimal way. The sweep efficiency decreases with the increasing of permeability contrast.
