Abstract Due to the huge differences between unconventional shale and conventional sand reservoirs in many aspects such as types characteristics of minerals, matrix pores fluids, construction rock physics model is significant for exploration development reservoirs. To make a better characterization gas-bearing reservoirs, we first propose new but more suitable characterize We then use well A demonstrate feasibility reliability proposed Moreover, brittleness indicator high-porosity organic-rich Based on parameter analysis using constructed model, finally compare with commonly used Young’s modulus content quartz organic matter, porosity, filled fluids. also index by integrating Poisson’s ratio. Tests real data sets that are sensitive than high-brittleness
