驱油用耐温抗盐丙烯酰胺聚合物的研究进展

Research Progress in Temperature and Salt-resistant Copolymers of Acrylamide Used for Enhanced Oil Recovery

从两性聚合物、耐温抗盐单体共聚物、疏水缔合聚合物、多元组合共聚物、共混聚合物和梳形聚合物等方面综述了近年来3次采油用耐温抗盐丙烯酰胺共聚物的研究进展,阐明了目前3次采油用丙烯酰胺类共聚物存在的不足,提出了3次采油用聚合物的发展方向。

The study on the copolymers for EOR could be divided into six types. They are amphoteric copolymer, temperature and salt-resistant monomer copolymer, hydrophobically associating copolymer, combined copolymer, blend polymer and comb-shaped cpolymer. The recent progress and current defect in copolymers of acrylamide for EOR are introduced. Finally, some suggestions about the further development are raised.
