摘　　要：以能与大庆原油产生超低界面张力的碱／表面活性剂／聚合物三元复合驱油体系为例，介绍了三元复合驱方案的设计与优化方法，包括化学剂碱、表面活性剂、聚合物的筛选及浓度确定，驱油试验效果评价。The design and optimization of alkaline/surfactant/polymer flooding formulations with ultralow interfacial tensions (ULIFTs) for EOR in Daqing Oil Fields are introduced and discussed extensively in this monographic paper . The topics covered are: selection of chemical species and establishment of their concentrations for ULIFTs at wide salinity ranges; chemicals in core flood tests for the formulations selected; their conformance with formation fluids and minerals; and reestablishment of injecting concentrations of each chemical in the formulations.
