Analysis of cross fracture seepage characteristics under different angle conditions

Based on the Weierstrass-Mandelbrot fractal function, multiple X-shaped fracture models with different intersection angles were established to investigate the fracture seepage characteristics under both equal and unequal inlet pressure conditions. The results showed that the intersection angle of the fractures influenced the flow contribution of each inlet branch to the rough and smooth outlet fractures, as well as the degree of convergence at the intersection.
