| 摘 要： | 研制了一种新型的PAC阳离子聚合物压裂液体系，对其配方与性能进行了研究。确定了PAC阳离子聚合物压裂液体系最佳配方：(0．30％～0．80％)PAC (0．05％．0．10％)HPAM (1．0HD％～2．0HD％)KCl 0．10％AE169 (0．05％～0．10％)TA—1，破胶剂可选用0．30％～0．50％的过硫酸铵溶液。该体系流变性能好，携砂能力强，粘土稳定性好，防乳破乳效果明显，具有很好的破胶性，破胶后水不溶性残渣含量低，对地层渗透率损害值很小，适应于粘土含量较高即存在水敏或低渗透油藏的油层压裂改造，取得了很好的现场应用效果。

| Abstract: | A new type of PAC cationic polymer fracturing fluid system was prepared. Its optimum formulation and properties were studied. The optimum formulation was as follows: (0.30% - 0.80%) PAC + (0.05% -0.10%) HPAM+ (1.00% -2.00%)KC1 + 0.10%AE169+ (0.05% -0.10%)TA- 1.0.30% - 0.50 % ammonium per-sulfate solution was selected as gel breaker. The system had good rheological property, sand - carrying capacity, clay stability, demulsification, and efficiency of gel breakdown. It had low water - undissolved residue content and little formation permeability damage. |
