文章描述了一系列在有或没有木质素磺酸盐预冲洗情况下的表面活性剂驱。为了隔离木质素磺酸盐作为牺牲剂的作用 ,设计了一种在液 -液界面抑制木质素磺酸盐作用的方法。实验结果包括 :木质素磺酸盐预冲洗段塞大小及降低表面活性剂滞留对提高原油采收率的关系。表面活性剂滞留损失的减少并不是提高采收率的直接原因 ,而是木质素磺酸盐作为有益的助表面活性剂和表面活性剂协同作用的结果。 The article describes a series of surfactant flooding in the presence or absence of lignosulfonate pre-rinse. To isolate the role of lignosulphonate as a sacrificial agent, a method of inhibiting lignosulphonate action at the liquid-liquid interface was designed. The experimental results include: lignin sulfonate pre-rinse slug size and reduce surfactant retention to improve the relationship between oil recovery. The reduction in surfactant retention loss is not the direct cause of enhanced oil recovery, but the result of the synergistic effect of lignosulfonate as a beneficial co-surfactant and surfactant.
