【摘要】 以丙烯酸（AA）、丙烯酰胺（AM）、2-丙烯酰胺基-2-甲基丙磺酸（AMPS）为原料,蒙脱土（MMT）为改性剂,过硫酸钾和无水亚硫酸氢钠为氧化还原引发体系,六亚甲基四胺(C₆H₁₂N₄)为交联剂,采用水溶液聚合法合成了一种新型高吸水聚合物凝胶型屏蔽暂堵剂（MTC-1）,其结构经IR表征。在最优合成条件（AM/AMPS/AA=11/7/1,m/m/m,引发剂加量0. 6 wt%,于45℃反应2. 5 h）下,MTC-1的最大吸水倍率为1006倍。岩心流动实验结果表明:MTC-1的堵水性能较高,封堵效率达到83. 72%。更多还原

【Abstract】 A novel super-absorbent polymer gel type shielding temporary blocking agent（ MTC-1） was synthesized by aqueous solution polymerization using AA,AM and AMPS as materials,MMT as modification agent,K₂S₂O₈ and NaHSO₃ as initiators,C₆H₁₂N₄ as crosslinker. The structure was characterized by IR. Under the optimal synthetic conditions（ AM/AMPS/AA = 11/7/1,m/m/m,initiators 0. 6 wt%,reaction at 45 ℃ for 2. 5 h）,the maximum water absorption ratio is 1006 times. Core flow experiment showed that MTC-1 exhibited well water shutoff performance with plugging ratio of 83. 72%.更多还原
