%X After volume fracturing of
horizontal wells in shale gas reservoir, an ex</span><span><span style=\"font-family:&quot;\">tremely complex fracture system is formed. The space
area of the fracture <span>system is the reservoir
reconstruction volume of shale gas reservoir. The</span> geometric parameters
such as crack length, crack width, crack height, and characteristic parameters
such as crack permeability and fracture conductivity proposed for a single
crack in conventional fracturing are insufficient to describe and characterize
the complex network fracture system after volume fracturing. In this paper, the
discrete fracture modeling method is used to establish the volume fracturing
network fracture model of horizontal wells in shale gas reservoir by using the
random modeling method within the determined reservoir space. The model is
random and selective, and can fully provide different forms of volume
fracturing fracture expansion, such as conventi<span>onal fracture morphology, line network model and arbitrarily distribut</span>ed
network fractures. The research results provide a theoretical basis for the
development plan and stimulation plan of shale gas reservoir, and have
important reference value and significance for other unconventional gas
reservoir fracturing.
