摘要:
为了更好的揭示BS无碱二元复合体系形成10-3数量级界面张力的组分用量界限,在大庆油田油藏温度、配制水矿化度等油藏条件下,利用Texas-500型旋滴界面张力仪对二元体系界面张力的影响因素进行表征。对聚合物分子量、浓度以及活性剂浓度进行正交实验研究。结果表明:聚合物相对分子质量及浓度对界面张力影响较大; 活性剂用量影响较小,质量浓度低至0.05%亦可形成10-3数量级; 随着配置水矿化度及剪切作用强度增加界面张力均呈现凹槽式变化。
Abstract:
To better reveal dosage limit of each component in non-alkali surfactant-polymer(SP)flooding system with ultra-low IFT,under the condition of Daqing Oilfield reservoir temperature and water salinity,influencing factors of IFT were studied by using Texas 500 type interfacial tensiometer.The orthogonal experiment results showed that relative molecular weight and solution concentration of polymer both are bigger impacts on IFT; concentration of surfactant solution is smaller one,low to 0.05% having a 10-3 magnitude of IFT; with the increase in water salinity and shear action,IFT showed a concave change.
