水力压裂已经成为一种改造油气层的重要方法，是油气井增产、注水井增注的有效措施。压裂液的性能好坏直接影响压裂施工的效果，合成聚合物压裂液稠化剂具有增稠能力强、悬砂能力强、对细菌不敏感、冻胶稳定性好、无残渣、对地层低伤害、低成本等特点，成为国内外研究的热门方向。合成聚合物主要包括丙烯酰胺类与聚乙烯醇类等，对丙烯酰胺类稠化剂研究主要集中在低分子量、酸性交联、疏水缔合以及提高抗温耐盐抗剪切性四个方面。

Hydraulic fracturing, which is the effective measures for enhanceding oil and gas well production and increasing water injection, has become one kind of the most important transformation methods for oil and gas layer. The performance of fracturing operation was directly affected by fracturing fluid. Since synthetic polymer fracturing fluid had plenty of superiority than regular Gung Gum fracturing fluid, such as better thickening ability, nice suspended sand capability, insensitive to the bacteria, gel has good stability, no residue, low to the formation damage and low cost etc., it became a hot direction of the research at home and abroad.Synthetic polymers included acrylamide with polyvinyl alcohol, etc., acrylamide class thickener research mainly concentrated in low molecular weight, acid cross-linked, hydrophobic association, and well salt resistance and shear resistance.
