摘　　要：在模拟大庆油田地层条件下，进行了水驱以及碱－表面活性剂－聚合物（ＡＳＰ）三元复合体系驱油效率的实验研究。在测定了配制不同碱、表面活性剂、聚合物浓度下的ＡＳＰ驱油效率基础上，分析了化学剂浓度对ＡＳＰ体系驱油效率的影响，并提出了适合于大庆油田三次采油需要的三元复合体系：碱（ＮａＯＨ）为８－１１ｇ／Ｌ，表面活性剂（Ｂ－１００）为１０ｇ／Ｌ，聚合物（３３３０Ｓ）为１０００ｍｇ／Ｌ。An experimental study was conducted about recovery efficiency on Brine flooding and Alkaline, Surfactant, Polyacrylamide flooding (ASP) in modeling Daqing Oil Field stratum. On the basis of measuring recovery efficiency in diffirent Alkaline, Surfactant, Polyacrylamide concentration, analysis has been made about the effect of chemical agent concentration on recovery efficiency in ASP flooding, and Alkaline, Surfactant, Polyacrylamide compound system is put forward to fit Daqing Oil Field.
