Hydraulic Fracture Propagation and Proppant Transport Mechanism in Interlayered Reservoir

Hydraulic fracture is crucial for assuring well production from unconventional reservoirs. For the optimization of hydraulic geometry and ensuing an interlayered reservoir, vertical propagation path has been analyzed. However, effective fluid channel cannot be formed if proppant unable to reach area where propagates. This paper presents a numerical model using lattice-based method investigate transport mechanism in The was simulated under different geological fracturing engineering factors. results indicate that interlayer Young’s modulus horizontal stress anisotropy are positively correlated with longitudinal carrying ability formations. injection rate optimal solution since too low unfavorable penetration interlayer, while high increases width instead further penetration. In conclusion, attention drawn fine particle size proppants used multi-layer reservoirs carry as far possible obtain maximum propped area.
