摘要
根据柳赞北区Es32+3断块高温、中渗油藏特点,进行了聚合物、表面活性剂以及二元复合驱体系配方的优选,主要对化学剂的高温稳定性、抗吸附性以及配伍性进行了评价。由此得到无碱二元复合驱体系为质量浓度为2000mg/L聚合物4#和质量分数为0.3%表面活性剂S3。
Based on the characteristics of the high temperature and medium permeability reservoir of the Es32 +3 fault block in the north of Liuzan, the polymer, surfactant, and the formulation of binary compound flooding system were optimized. The lab research is mainly about high-temperature stability,antiadsorption and compatibility of the chemical flooding formula, including polymer,surfactant and binary composite system. The optimalalkali-free binary chemical flooding formula :2000 mg/L polymer 4 # and0.3% surfactant S3.
