复配型驱油剂的室内模拟实验研究

Laboratory simulating the waterflood recovery for the combined oil displacement agent

以正交实验法将黑液与表面活性剂二苯胺磺酸钠、碱进行复配,通过室内模拟驱油实验测定采收率。实验结果表明,当二苯胺磺酸钠质量含量为0.6%,黑液质量含量为1.8%,NaOH质量含量为0.4%时,采收率可达84.40%。

Black liquor was combined with the surfactant and the alkali by the orthogonal design. The oil recovery factor is determined by the laboratory simulating the waterflood recovery. The experimental results show that the diphenylamine sulfonic acid sodium quality content is 0.6%, the black liquor quality content is 1.8% ,the NaOH quality content is 0.4% ,the oil recovery can reach 84.4%.
