Preparation and Rheological Behavior of Temperature-Resistant Hydroxypropyl Guar Gum Supramolecular Hydrogels Based on Dynamic Borate Ester Bonds
The increasing depth of oil wells and associated elevated formation temperatures pose significant challenges to conventional crosslinked polymer gels used in hydraulic fracturing, as viscosity degradation severely impairs proppant transport and stimulation efficiency. In this study, a thermally stable organic boron cro...
