泡沫驱油技术室内实验及参数优化研究

Indoor experiments and parameter optimization of foam flooding

通过起泡剂评价,优选出质量浓度为0.5%的QP-2为目标油藏用起泡剂。泡沫驱用起泡体系最佳气液比为1:1,最佳注入量为0.8PV,最佳注入速度为0.5mL/min,最佳注入方式为交替注入。

QP-2with the mass concentration of0.5%was selected as the foaming agent for the target reservoir by evaluation on the foaming agent.The optimal gas liquid ratio of foam flooding system is1:1,the optimal injection rate is0.8PV,the optimal injection rate is0.5mL/min,and the best mode is alternating injection.
