一种丙烯酰胺共聚物及其制备方法与应用
摘要：
本发明涉及油田化学品领域，公开了一种丙烯酰胺共聚物及其制备方法与应用。其中丙烯酰胺共聚物含有结构单元A、结构单元B和结构单元C，其中，所述结构单元A为式Ⅰ所示的结构单元，所述结构单元B为式Ⅱ所示的结构单元，所述结构单元C为式Ⅲ所示的结构单元；且以所述丙烯酰胺共聚物的总重量为基准，所述结构单元A的含量为43.5～98重量％，所述结构单元B的含量为0.6～39重量％，所述结构单元C的含量为0.6～39重量％。该丙烯酰胺共聚物的水溶性良好，且具有热增稠作用，适用于作为高温高盐油藏三次采油用热增稠剂使用，
摘要（英）：

The invention relates to the field of oil field chemicals and discloses an acrylamide copolymer as well as a preparation method and an application thereof. The acrylamide copolymer contains a structure unit A shown in the formula I, a structure unit B shown in the formula II and a structure unit C shown in the formula III; on the basis of the total weight of the acrylamide copolymer, the content of the structure unit A is 43.5wt%-98wt%, the content of the structure unit B is 0.6wt%-39wt%, and the content of the structure unit C is 0.6wt%-39wt%. The acrylamide copolymer has good water solubility and a thermothickening function and is applicable to three-time oil recovery of a high-temperature and high-salinity reservoir as a thermothickener.
