摘　　要：实验测定了298K和318K进口磺酸留盐型驱油剂ORS-41和B-100在油砂上的吸附等温线，并研究了NaOH和NaCl对吸附量的影响．实验结果用非均匀表面两阶段吸附模型导出的吸附等温方程式关联，计算值和实验值符合良好．The adsorption isotherms of surfactants for EOR (ORS--41 and B--100) on oilsand at 298 K and 318 K were measured. The effect of NaOH or NaCI on adsorption hasbeen observed. By using the adsorption isotherm equahons derived from the nonuniformsurface two step adsorption model, the correlation of cxpcrimcntal isotherms are realized.The agreement between calculated results and experimental data is good.
