Abstract:

The static and dynamic adsorption law and chromatographic separation character of flooding system of Shengli petroleum sul-fonate(SLPS) and assistant surfactant have been studied. Re-sups show that SLPS is linear adsorption at lower concentration,and maximum adsorption capacity is 4. 6 mg/L. The adsorption capacity has been reduced obviously when adding assistant sur-factant. There is chromatographic separation in some extant
when inject SLPS and assistant surfactant together, the effect of chromatographic separation is more obvious when adding HPAM in flooding system. According to the experiments, the coopera-five effect will exhibit by increasing the surfactant concentration of the flooding liquid.

Key words: petroleum sulfonate, dynamic adsorption, chromatographic separation, surfactant/polymer flooding
