Developing an inexpensive and efficient hydrocarbon thickener for carbon dioxide (CO₂) is of great significant to optimize the carbon dioxide enhanced oil recovery technology. A new hydrocarbon thickener propylene oxide-glycidyl phenyl ether copolymer was prepared based on the CO₂-philic propylene oxide oligomer and mildly CO₂-phobic phenyl group. The phase behavior of the polyether thickeners in CO₂ and their thickening performance on CO₂ were investigated in terms of the copolymer composition and molecular weight. The results were shown that the polyether thickeners cause an excellent enhancement in CO₂ viscosity, and there exists an optimal composition with the greatest thickening effect.

开发廉价且有效的用于二氧化碳（CO ₂）的烃类增稠剂对于优化二氧化碳增强的采油技术具有重大意义。基于亲CO ₂环氧丙烷低聚物和轻度CO ₂憎水苯基制备了一种新型的烃类增稠剂环氧丙烷-缩水甘油基苯基醚共聚物。在CO聚醚增稠剂的相行为₂和CO它们的增稠性能₂在该共聚物组合物和分子量方面进行了研究。结果表明，聚醚增稠剂可显着提高CO ₂含量 具有最佳的增稠效果的最佳组成。
