Organic-rich shale reservoirs usually have complex mineral compositions and pore system in a small scale.This study presents a workflow of the fracture properties and anisotropy parameter inversion of shales based on the rock physics model and improved particle swarm optimization algorithm.A two-pore system for fractured shales was built through applying the self-consistent equivalent medium theory and Chapman's multi-scale porosity model.This inversion workflow can be used to estimate multi-parameter simul...
