摘　　要：以自制石油磺酸盐为主剂,通过优选助剂提高其增溶及界面性能,得到复合驱油剂YCQY-103。YCQY-103与磺酸盐型驱油剂CDMP-2和某油田现场用驱油剂CQH-1相比,界面张力、润湿性能、毛细管举升高度、渗吸等性能均有明显改善;YCQY-103在注入量为0.8 PV、浓度0.3%、渗透率为10 mD的条件下,增采率可达12.18%。A composite oil displacement agent YCQY-103 was obtained by using self-made petroleum sulfonate as the main agent and optimizing additives to improve its solubilization and interface performance.Compared with the sulfonate type oil displacement agent CDMP-2 and the on-site oil displacement agent CQH-1 in a certain oilfield,YCQY-103 has significantly improved interfacial tension,wetting performance,capillary lift height,and permeability.Under the conditions of injection volume of 0.8 PV,concentration of 0.3%,and permeability of 10 mD,YCQY-103 achieved an enhanced recovery rate of 12.18%.
