| 摘 要： | 由疏水缔合聚合物AP–P4 和酚醛树脂预聚体YG103 交联得到了酚醛树脂冻胶，研究了酚醛树脂冻胶的流变性和粘弹性，并对疏水缔合聚合物和酚醛树脂冻胶的粘弹性进行了对比。研究表明，酚醛树脂冻胶成胶过程可分为缓慢诱导阶段、快速增长阶段和稳定阶段。酚醛树脂冻胶的剪切应力具有时间依赖性和滞后特性，在外力作用一段时间后冻胶的应变可较好地恢复。与聚合物溶液相比，酚醛树脂冻胶具有更宽的线性粘弹性区域和更高的储能模量和损耗模量。在低频率下该冻胶的储能模量比损耗模量大，随着频率的增加，储能模量和损耗模量均增加；随着聚合物和交联剂质量分数的增加，冻胶体系的储能模量和损耗模量 均增加；随着矿化度的增加，冻胶体系的储能模量和损耗模量出现先降低—增加—降低的过程。

| Abstract: | Hydrophobic-lipophobic proppant can be obtained by immersing all kinds of proppant among hydrophobic-lipophobic treatment fluid such as ceramsite and quartz sands.Mechanism of hydrophobic-lipophobic treatment fluid on molecular constitution is analyzed，and the agent treatment process and chemical stability，hydrophobicity，lipophobicity，proppant carrying capacity and flow conductivity of hydrophobic-lipophobic proppant are introduced.The result shows that hydrophobic- lipophobic proppant can diminish the possibility of block.Therefore，the fracture can maintain higher flow conductivity and prolong validity of fracturing at the same time. |
