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.
