Provided herein are liquid polymer (LP) compositions comprising a synthetic (co)polymer (e.g., an acrylamide (co)polymer), as well as methods for preparing aqueous polymer solutions by combining these LP compositions with an aqueous fluid. The resulting aqueous polymer solutions can have a concentration of a synthetic (co)polymer (e.g., an acrylamide (co)polymer) of from 50 to 15,000 ppm, and a filter ratio of 1.5 or less at 15 psi using a 1.2 μm filter. Also provided are methods of using these aqueous polymer solutions in oil and gas operations, including enhanced oil recovery.
本文提供了包含合成(共)聚合物(如丙烯酰胺(共)聚合物)的液态聚合物(LP)组合物,以及通过将这些 LP 组合物与水性流体结合制备聚合物水溶液的方法。所得聚合物水溶液的合成(共)聚合物(如丙烯酰胺(共)聚合物)浓度为 50 至 15,000 ppm,使用 1.2 μm 过滤器在 15 psi 压力下的过滤比为 1.5 或更低。此外,还提供了在石油和天然气作业(包括提高石油采收率)中使用这些聚合物水溶液的方法。
