Plugging Performance and Retention Mechanism of Composite Bridging Materials for Water-Based Drilling Fluids in High-Temperature and High-Pressure Fractured Formations
Lost circulation in fractured formations remains a critical challenge in oil and gas drilling, particularly under high-temperature and high-pressure (HTHP) conditions. For this study, we systematically evaluated the physicochemical properties of commonly used bridging materials and optimized rigid, flexible, and fibr...
