Experimental study reveals enhanced mechanical properties of nanomaterial-enabled polymer gel in severe lost circulation scenarios, suggesting improved plugging effectiveness.
Key Points
The novel coupling system achieves effective plugging in large fractures, outperforming traditional methods.
Experimental results show a maximum pressure capacity of 8 MPa for a 7 mm fracture using the coupled approach.
The study employs orthogonal experiments to optimize gel composition and analyze mechanical stability with nanosilica enhancement.
These findings emphasize the potential of combining polymer gel and bridging solids in complex geological environments.
