| 摘 要： | 采用两相滴定法分别考察磺酸盐驱油剂在砂岩表面的吸附损失及在多孔隙砂岩中的驱动损耗。结果表明:磺酸盐类驱油剂在砂岩表面的吸附损失主要与砂岩的表面积正相关;在驱动过程中,多孔隙介质的孔隙体积及孔喉结构是造成驱油剂滞留损失的主要原因;在砂岩表面的吸附及在多孔隙介质中的滞留都会使驱油剂在溶液中的有效质量浓度急剧减小;通过组分间的增溶作用,增加磺酸盐驱油剂在水相中的溶解性能,减少溶液中游离分子的数量,能够降低磺酸盐驱油剂的损失。

| Abstract: | The adsorption loss on the surface of sand and the retention loss of commixture sulfonates used for oil displacement in porous sand were respectively investigated by using two-phase titration method.The results show that the adsorption loss of sulphonate oil displacement agent is mainly relevant to surface area of sand surface.However,the retention loss caused by the pore volume and the structure of pore throat is the dominant factor in flooding process.The adsorption on sand surface or the retention in por... |
