缔合聚合物溶液岩芯剪切流变行为研究

针对疏水型缔合聚合物和普通线性高分子聚合物两种不同分子结构的聚合物，开展了岩芯剪切对聚合物溶液流变行为的影响研究。测试了剪切前两种聚合物溶液的流变曲线，分析了流变特性。用人造岩芯进行了岩芯剪切实验，测试了剪切后的聚合物溶液各自的流变曲线并进行了对比分析。将剪切后的聚合物溶液进行了阻力系数和残余阻力系数测试，以 模拟经地层剪切后聚合物溶液在油层深部的变化状况。研究结果对聚合物驱具有重要参考价值和指导意义。

CORE SHEARING RHEOLOGY BEHAVIOR OF ASSOCIATING POLYMER SOLUTION

Effect of rock coreshearing for hydrophobically associating polymer and the ordinary linear high molecule polymer solution on polymer solution rheology behavior is studied, the rheology curves of two types of polymer solution before sheared is tested, and the rheology property is analyzed. Manmade cores are used to test coreshearing, rheology cures of sheared polymer solutions are tested and rheology properties analyzed by comparison. And then, to imitate the situation of polymer solution in the deep oil reservoir after layer shearing, the resistance factor and residual resistance factor experiments of coreshearing polymer solutions are determined. The researches have important value and implications for EOR.
