摘要
利用物理模拟实验,针对多种表面活性剂进行界面特性筛选,以找出适合大庆油田的二元体系用表面活性剂。实验表明,SHSA-HN2表面活性剂能够有效降低界面张力,比石油磺酸盐SS降低界面张力的能力要强。并且SHSA-HN2二元体系的粘度和弹性均高于石油磺酸盐ss二元体系。从驱油效果实验可以看出,SHSA-HN2表面活性剂二元体系的驱油效果比单独聚合物驱提高3.8个百分点,SHSA-HN2表面活性剂二元体系的驱油效果与石油磺酸盐ss二元体系相比,石油采收率提高2.3%。SHSA-HN2表面活性剂二元体系在大庆油田上具有较好的驱油效率,该实验结果对于大庆油田二元驱具有实际意义。
The physical simulation experiment was used to screen the interface characteristics of various surfactants in order to find the suitable ones for the binary system of Daqing oilfield. The experiment results indicated that SHSA-HN2 could effectively reduce interfacial tension, which was better than the mahogany petroleum sulfonate SS. And the viscidity and elasticity of the SHSA-HN2 were both above the mahogany petroleum sulfonate SS binary system. According to the oil displacement efficiency, SHSA-HN2 binary system＇s oil displacement efficiency was 3.8% higher than individual polymer flooding and 2.3% higher than mahogany petroleum sulfonate SS binary system. SHSA-HN2 binary system has better oil displacement efficiency in Daqing oilfield, and the results of experiment have practical significance for the binary flooding of Daqing oilfield.
