高30油藏二元复合体系化学剂的静态吸附

The static adsorption of binary composite system chemical agent in reservoir G30

在高30高温油藏条件下,测定了固液界面吸附量和二元复合体系等温吸附曲线。结果表明,缔合聚合物HNT201-3和表面活性剂CDS-1在二元复合体系中的吸附规律和特征,都符合朗格缪尔等温吸附曲线。得出了聚合物的吸附平衡浓度为1000mg/L,表面活性剂吸附平衡浓度为0.05%,对驱油体系中各化学剂浓度的确定起到了指导作用。

In the high temperature of reservoir G30 the conditions, it determined solid-liquid interface adsorption and binary composite system isotherm curve. The results showed that the adsorption Law and features of associating polymer HNT201-3 and surfactant CDS-1 in the binary complex system accord with Langmuir isothermal adsorption curve, and we reached the equilibrium concentration of polymer was 1000 mg/L and the equilibrium concentration of surfactant was 0.05 %,It played a guiding role on the chemical agent concentration determination of displacement systems.
