摘要

为了提高疏水缔合聚合物（HAP）的流变性能和在多孔介质中的流度控制能力

将环糊精和环氧氯丙烷缩聚得到一种水溶性的环糊精聚合物（β-CDP）

并将其与HAP混合。结果表明

环糊精聚合物与疏水缔合聚合物之间的主客体包合作用大幅改善了疏水缔合聚合物溶液的增黏能力和黏弹性

并且主客体包合体系（β-CDP/HAP）保持了显著的剪切稀释性。β-CDP/HAP表现出独特的黏—温关系

其黏流活化能随温度变化

表现出极强的耐温能力。岩心流动实验表明

β-CDP/HAP在多孔介质中形成多层吸附

比HAP具有更强的流度控制能力。通过疏水基团和环糊精基团之间的主客体作用来可以增强分子间的相互作用

能提高缔合聚合物的综合性能。

Abstract

In order to improve the rheological properties of hydrophobically associating polymers（HAP） and the mobility control ability in porous media

a water-soluble cyclodextrin polymer

β-CDP. is synthesized by condensation of the cyclodextrin and epichlorohydrin

meanwhile

mixed with the HAP. The results showed that the host-guest interaction improves the thickening ability and viscoelasticity of the HAP solution. The host-guest inclusion system of β-CDP and HAP maintained shear thinning behavior. β-CDP/HAP demonstrated special viscosity-temperature curves and its activation energy changes with temperature

showing a strong ability of temperature resistance. The core flooding experiments showed that β-CDP/HAP formed multilayer adsorption in porous media and had stronger mobility control ability than HAP. By the host-guest interaction between the hydrophobesp and the cyclodextrin groups

the intermolecular interaction can be enhanced

and the comprehensive performance of HAP can be improved.
