Compared with the traditional water-based fracturing fluid thickener guanidine gum, the price of synthetic polymer is relatively low, and the temperature resistance, shear resistance and viscoelasticity of the formed fracturing fluid are better. Therefore, the fracturing fluid formed by the crosslinking of HPAM and organic metal crosslinker will become one of the hot spots in the research of water-based fracturing fluid. In this paper, zirconium oxychloride, acetic acid and triethanolamine were used as raw materials to prepare organic Zr-crosslinked agent. The polymer gel was formed by crosslinking the organic Zr-crosslinked agent with the acrylamide copolymer KY-5S solution, and the viscosity of the gel with different concentrations was investigated. The performance of the fracturing fluid was evaluated through laboratory experiments. The results showed that the viscosity of the fracturing fluid remained above 100 mPa s at the shear rate of 170 s⁻¹ and after 2 h of shear at 140 °C. When the temperature was 20 °C, the shear stress was 0.1 Pa, and the frequency f varied from 0.1 to 10 Hz, the elastic modulus of fracturing fluid was at least 11.6 Pa, and the viscous modulus was at least 8.54 Pa. At the temperature of 90 °C, when the addition of glue breaker was 0.01 wt%, the longest breaking time was 3 h, and the maximum viscosity of breaking liquid was 4.05 mPa s. The damage rate of core permeability of glue breaker was about 13%. When the temperature was 25 °C and the shear rate was 0–170 s^-1, the viscosity of fracturing fluid remained above 200 mPa s.

与传统的水基压裂液增稠剂胍胶相比，合成聚合物价格较低，所形成的压裂液的耐温性，抗剪切性和粘弹性较好。因此，由HPAM与有机金属交联剂交联形成的压裂液将成为水基压裂液研究的热点之一。本文以三氯氧化锆，乙酸和三乙醇胺为原料制备有机锆交联剂。通过将有机Zr交联剂与丙烯酰胺共聚物KY-5S溶液交联而形成聚合物凝胶，并研究了不同浓度的凝胶的粘度。通过实验室实验评估了压裂液的性能。  在170  s ^-1的剪切速率下以及 在140  °C剪切2 h后的mPa s 。当温度为20  °C时，剪应力为0.1  Pa，频率f在0.1至10  Hz之间变化，压裂液的弹性模量至少为11.6  Pa，粘性模量至少为8.54  Pa。在90  °C的温度下，破胶剂的 添加量为0.01 wt％时，最长的破胶时间为3  h，破胶液的最大粘度为4.05  mPa  s。破胶剂的芯渗透率的破坏率约为13％。当温度为25  °C且剪切速率为0–170  s ^-1时，压裂液的粘度保持在200  mPa  s以上。
