摘要
针对高温、高矿化度、高钙镁含量的中原文明寨油田，筛选出了非离子表面活性剂ＮＳ体系作为驱油剂。本文报道了ＮＳ在文明寨油藏油砂和岩心上的静、动态吸附实验结果。
onionic surfactant NS, a fatty acid arkanol amide polyglycol ether, has chossen as flooding chemical for hostile reservoirs of Wenmingzhai Oil Fields in Zhongyuan. In this paper the adsorption of NS from solutions in distiled water, 1% NaCl salt water and a typical formation water at 65℃ on oily sands is investigated under static condition and on reservoir cores under dynamic condition. The amounts of adsorbed NS is both cases are determined and appear to be not high. The adsorption isoterm of NS on oily sands is of Langmuir type.
