This analysis demonstrates optimal particle sizes and concentrations that improve sealing in fractured formations, suggesting enhanced drilling efficiency.

Key Points

The aim is to investigate the mechanisms of particle transport and sealing in fractured strata to address fluid loss during drilling.
Establish a multi-scale research system incorporating indoor experiments and CFD-DEM numerical simulations.
Develop a dynamic sealing model utilizing Di Felice drag force and modified JKR contact theory.
Analyze various particle sizes, distributions, and concentrations effects on sealing efficiency.
Optimal particle size for sealing is between 1/2 to 2/3 of the fracture width, as per the one-third bridging theory.
A triple-particle distribution with 70%-80% dominant particles yields the highest pressure capacity.
The optimal concentration of the sealing agent is 8% to avoid sealing failure or false plugging.
