研究了改性碱木质素HML和各种石油磺酸钠的吸附特性，以及作为三次采油牺牲剂减少石油磺酸钠吸附损失的作用规律，获得了改性碱木质素与大庆四厂原油产生超低界面张力的条件。结果表明：HML作为牺牲剂可以显著地减少主表面活性剂石油磺酸钠ORS-41的吸附损失(减少量＞50 ％），HML能和石油磺酸钠、碱、聚合物配合将油水界面张力降至超低范围。改性碱木质素作为三次采油牺牲剂具有广泛的应用前景。

The absorption characteristics of modified lignin(HML,self-prepared) and petroleum sulfonates were studied，and the effect of factors of HML as sacrificial agent on absorption decrease of surfactant was also investigated.The optimum formulation of ASP was obtained.The results showed that the absorption loss of surfactant(especially for ORS-41) on the formation rock can be inhibited significantly(more than 50 %) by the preflush or in admixture with the chemical recovery materials,the solution of HML mixed with ORS-41,alkali and polymer can reach hyper-low interfacial tension.Therefore the modified lignin has bright prospect as sacrificial agent in the tertiary oil recovery.
