人工合成聚丙烯酰胺和天然植物胶如瓜尔胶等常作为压裂液稠化剂，与瓜尔胶等天然植物胶相比，丙烯酰胺类人工合成稠化剂因其在性能、价格、清洁程度方面更具优势，而在油田压裂作业中广泛使用。对丙烯酰胺类压裂液稠化剂进行了调研，根据聚丙烯酰胺类压裂液稠化剂参与合成的反应单体数目进行了分类(1~5种)，总结了丙烯酰胺类压裂液稠化剂的合成方法、合成条件，并对部分反应单体增效原因进行了解释，提出了在合成时缺少竞聚率测定、缺少对聚合物进行结构设计等问题，而这可能是影响其性能的关键。该研究可为合成丙烯酰胺类压裂液稠化剂时单体选择、合成方法提供参考。

Artificially synthesized polyacrylamides and natural plant gums such as guar gum are often used as fracturing fluid thickeners. Compared with natural plant gums such as guar gum, artificially synthesized polyacrylamides have distinct advantages in terms of performance, cost, and environmental cleanliness, as a result, they are widely used in hydraulic fracturing operations in oilfields. The acrylamide fracturing fluid thickeners were investigated, and then classified according to the number of reaction monomers involved in the synthesis of polyacrylamide fracturing fluid thickeners (ranging from 1 to 5). The synthesis methods and conditions for the acrylamide fracturing fluid thickeners were summarized, and the reasons for the synergy of some reaction monomers were explained. Furthermore, certain issues, such as the lack of reactivity ratio measurement and the absence of structural design of the polymers, in the synthesis process wore proposed, which may be critical factors affecting their performance. This research can serve as a reference for selecting monomers and synthesis methods when synthesizing acrylamide fracturing fluid thickeners.
