摘要
采用旋转滴法测定了胜利石油磺酸盐与不同区块原油的油水界面张力,考察了有机碱乙醇胺及聚合物对体系界面张力的影响,测定了复合驱体系的粘度。实验结果表明,乙醇胺和胜利石油磺酸盐之间存在降低油水界面张力的协同效应,在适宜的乙醇胺浓度条件下,界面上的石油酸、反应生成的石油酸皂和石油磺酸盐混合吸附,界面张力达到最低。聚合物对界面张力总体影响不大。有机碱三元复合驱体系的粘度变化不大。
The interracial tension between Shengli petroleum sulfonate and Shengli crude oils from different blocks were investigated using spinning drop method. The effects of organic alkali ethanolamine and polymer on interfacial tension were studied. The viscosities of combination flooding systems were measured. The experimental results showed synergistic effect in lowering interracial tension between ethanolamine and Shengli petroleum sulfonate. Under appropriate ethanolamine concentration, the mixed adsorption of petroleum acid, in situ produced soap and petroleum sulfonate give rise to the lowest interracial tension value. Various kinds of polymers have little impact on the interracial tension. The viscosity of organic alkali ASP flooding system does not change significantly.
