The flooding effect of ASP is studied in third class oil layer. The surfactant concentration of weak alkali ASP ranges from 0.0166% to 0.4% to reach ultra-low interfacial tension by laboratory evaluation of weak alkali ASP.
又探讨了三类油层的三元复合驱油效果,通过弱碱三元体系室内性能评价,确定了弱碱三元复合体系产生超低界面张力表面活性剂的浓度范围为0.0166%～0.4%、Na_2CO_3的浓度范围为0.4%～1.2%,并通过表面活性剂吸附量对界面张力的影响,确定了经过多次吸附后,石油磺酸盐弱碱三元复合体系仍然具有较低的界面张力。
