'''聚丙烯酰胺'''（PAM）是一种线型高分子聚合物，[[化学]]式为(C3H5NO)n。在常温下为坚硬的玻璃态固体，产品有胶液、胶乳和白色粉粒、半透明珠粒和薄片等。热稳定性良好。能以任意比例溶于水，水溶液为均匀透明的液体。长期存放后会因聚合物缓慢的降解而使溶液粘度下降，特别是在贮运条件较差时更为明显。

聚丙烯酰胺作为润滑剂、悬浮剂、粘土稳定剂、驱油剂、降失水剂和增稠剂，在[[钻井]]、酸化、压裂、堵水、固井及二次采油、三次采油中得到了广泛应用，是一种极为重要的油田化学品。<ref>[https://www.360kuai.com/pc/93668d09192360a12?cota=3&kuai_so=1&sign=360_7bc3b157&refer_scene=so_55 聚丙烯酰胺投加量越多，效果越好吗 ],快资讯 , 2022-02-24</ref>
