| 摘 要： | 石油磺酸盐表面活性剂驱油时在油藏中的吸附损耗、色谱分离会直接影响复合驱油体系协同效应的发挥，从而影响驱油效果。为此，用动态吸附实验考察了石油磺酸盐表面活性剂浓度对油砂吸附量的影响；考察不同长度填砂模型对胜利石油磺酸盐与助剂1^#混合物的色谱分离现象。结果表明，胜利石油磺酸盐浓度在10g/L以上时，油砂吸附量最大达4．8mg／g；胜利石油磺酸盐与助剂1^#之间存在色谱分离现象，且填砂模型越长，分离越明显，说明现场应用时，只要适当增加注入液浓度，复配协同效应可得到发挥。

| Abstract: | The adsorption and chromatographic separation of Shengli petroleum sulfonate(SLPS) had negative effects on the synergism of compounded flooding system and recovery of oil. The changes of adsorption capacity with the concentration of SLPS were examined by using dynamic adsorption experiment,and chromatographic separation of SLPS and 1 # assistant surfactant was also studied. The result showed the maximum adsorption of SLPS was up to 4.8 mg/g at the concentration over 10 g/L, and there was chromatographic separation between SLPS and 1 # assistant surfactant, which didn't affect the recovery by increasing the surfactant concentration in flooding liquid. |
