深层碳酸盐岩油气藏是目前油气增储上产的重要支撑。超深、超高温储层环境对储层改造酸化技术提出了更高的技术要求。而且，胶凝酸是高温储层酸化改造的主要酸液，耐温不超过180 ℃，胶凝剂是制约其耐高温性能的关键因素之一。本文以丙烯酰胺（AM）、AMPS、二甲基二烯丙基氯化铵（DMDAAC）和NVP为单体、氧化剂和还原剂，通过聚合反应制备了耐高温聚合物凝胶。同时，以环氧树脂为壁材，采用原位聚合法制备了微胶囊。室内性能评价结果表明，该胶凝剂易溶于高浓度酸溶液，具有良好的增粘效果。在180 °C和170 s-1剪切速率下，将0.8%质量分数的胶凝剂溶解在20%质量分数的盐酸中。剪切60 min后，粘度保持在22.45 mPa·s左右，表现出良好的耐温性和抗剪切性，性能优于现有常用胶凝剂产品上级。
Deep carbonate rock oil and gas reservoir is an important support for increasing oil and gas storage and production at present. The environment of ultradeep and ultrahigh-temperature reservoirs has put forward higher technical requirements for reservoir modification acid technology. Moreover, gelling acid is the main acid solution for high-temperature reservoir acidizing transformation, with a temperature resistance of no more than 180 °C, and the gelling agent is one of the key factors restricting its high-temperature resistance performance. In this paper, AM, AMPS, DMDAAC, and NVP were used as monomers, oxidants, and reducing agents to prepare a high-temperature-resistant polymer gel through polymerization. At the same time, microcapsules were prepared by in situ polymerization using epoxy resin as the wall material. The indoor performance evaluation results indicate that the gelling agent is easily soluble in high-concentration acid solution and has good viscosity increasing effect. At 180 °C and 170 s–1 shear rate, 0.8% mass fraction of the gelling agent was dissolved in 20% mass fraction of hydrochloric acid. After shearing for 60 min, the viscosity remained at about 22.45 mPa·s, demonstrating good temperature resistance and shear resistance, and its performance was superior to existing commonly used gelling agent products.
