中文摘要：

通过Turbiscan稳定性分析仪测得的稳定性常数（TSI-1）比较不同驱油剂质量浓度下黏土矿物的悬浮稳定性，结果表明表面活性剂对黏土悬浮稳定性影响最大。通过不同驱油剂体系下表面活性剂在黏土矿物表面的吸附变化和黏土矿物表面Zeta电位的变化，分析三元复合驱采出水中黏土矿物的稳定机理。结果表明，采出水中表面活性剂在黏土表面的吸附为Langmuir型吸附；随聚合物、碱质量浓度增大，表面活性剂在黏土表面的吸附量降低、黏土矿物表面Zeta电位绝对值增大，但碱、聚合物对表面活性剂吸附量的影响较小；采出水中三元驱油剂的存在增强了黏土矿物的悬浮稳定性。

英文摘要：

Stability of clay mineral suspensions with different mass concentrations of oil displacing agent was compared via their stability constants （ TSI - 1 ） measured with Turbiscan stability analyzer. The resulted TSI - values showed that the surfactants display the greatest effect on clay mineral suspension stability. Mechanism for the stabilization of clay mineral particles suspended in water collected from ASP flooding was investigated via the changes of surfactant adsorption and Zeta potential on the clay mineral particles surface. The results showed that, the surfactants adsorbed onto surface of clay mineral particles in collected water belong to Langmuir type adsorption. Following the increase of mass concentrations of alkali and/or polymer, the surfactant adsorption on clay mineral particles surface decreases, while the absolute value of Zeta potential on clay mineral particles surface increases. However, the effect of alkali and/or polymer on amount of surfactant adsorbed is relatively small. The existence of the ternary oil displacement agent in the collected water increases the stability of the clay mineral particles suspension.
