Temperature-Activated Acid Thickening Agent Based on Grafted Cellulose Derivatives for Stimulation of High-Temperature Carbonate Reservoirs
To address the challenges of rapid acid depletion and limited stimulation range caused by high temperatures during acid fracturing in deep carbonate reservoirs, this study synthesized a temperature-responsive smart acid thickener, CMHM (cationic-modified hydroxypropyl methylcellulose), based on renewable cellulose de...
