强化采油中常用的表面活性剂石油磺酸盐在通过油层时会发生色谱分离作用 ,其完整性受到破坏 ,从而影响与原油界面的活性。采用高效液相色谱法 (HPLC) ,通过测定磺酸盐色谱分离因子 ,定量地描述石油磺酸盐在岩心多孔介质的色谱分离程度。应用该方法可以考察影响色谱分离因子的因素 ,以优化化学驱油配方的设计。该方法具有灵敏度高、可靠、用量少等特点 The commonly used surfactants in enhanced oil recovery Petroleum sulfonates undergo chromatographic separation as they pass through the reservoir, compromising their integrity and affecting the activity at the interface with the crude oil. High performance liquid chromatography (HPLC) was used to quantitatively describe the chromatographic separation of petroleum sulfonate in porous media by determining the sulfonate chromatographic separation factor. This method can be used to examine factors that affect the chromatographic separation factor to optimize the design of chemical flooding formulations. The method has high sensitivity, reliability, less dosage and so on
