AI Article Synopsis
- A hydrophobically associative polymer (HAP) was combined with β-cyclodextrin and epichlorohydrin polycondensate (β-CDP) to boost intermolecular interactions in water, improving thickening and viscoelastic properties.
- The resulting host-guest inclusion system showed unique viscosity-temperature characteristics and variable activation energy, enhancing the solution's performance in oil recovery applications.
- Tests indicated that the β-CDP/HAP mixture outperformed pure HAP and other solutions, achieving a 5.5% and 9.3% greater oil recovery than HAP and a partially hydrolyzed polyacrylamide solution, respectively, making it more effective for high-temperature oil extraction.
Article Abstract
In this work, a hydrophobically associative polymer (HAP) was mixed with β-cyclodextrin and epichlorohydrin polycondensate (β-CDP) in an aqueous solution to enhance the intermolecular interaction through host-guest inclusion between hydrophobes and cyclodextrins. Results showed that the host-guest interaction improved the thickening ability and viscoelasticity of the HAP solution and maintained its shear thinning behavior. The host-guest inclusion system demonstrated special viscosity-temperature curves and variable activation energy. Enhanced oil recovery (EOR) performance tests showed that the oil increment produced by the host-guest inclusion system was 5.5% and 9.3% higher than that produced by the HAP and the partially hydrolyzed polyacrylamide solution, respectively. Compared with pure HAP, β-CDP/HAP has a better comprehensive performance and is more attractive for EOR in high-temperature reservoirs.
