Experimental results demonstrate a gel-resin composite's effectiveness in improving plugging material for lost circulation, suggesting enhanced stability in high-pressure formations.
Key Points
The gel-resin composite achieved a compressive strength of 5.04 MPa when contaminated with drilling fluid, indicating robust performance under challenging conditions.
Rheological tests revealed a shear-thinning behavior; the composite maintained low viscosity for improved pumpability while ensuring stability at elevated temperatures.
Pressure-bearing tests confirmed a breakthrough pressure of 15.19 MPa in fractures, showing effective sealing under rigorous environmental demands.
This gel-resin composite offers an eco-friendly alternative for mitigating lost circulation in drilling, with significant engineering implications in complex formations.
