Synthesis and Performance Evaluation of SF-4 Spacer Fluid for Open-Hole Completion with Oil-Based Drilling Fluid in the East China Sea

As oil and gas exploration and development in the East China Sea advance toward deeper and hotter formations, direct contact between oil-based drilling fluid and water-based completion fluid can cause severe rheological incompatibility during open-hole completion. This study developed an amphiphilic SF-4 spacer based o...

Multi-Field Coupled Fracture Propagation Mechanisms of Supercritical CO2 Fracturing in Gulong Shale and Tight Sandstone

Strong heterogeneity in unconventional reservoirs leads to complex fracture propagation and challenges in quantitative stimulation evaluation. This study integrates true triaxial fracturing experiments, three-dimensional CT reconstruction, multi-field coupled numerical simulation, and multiple linear regression to inve...
