摘要
•A DAGP model is proposed based on shale geostatistical and petrophysical data.•A representative model is constructed by fractal organic matter particles.•DAGP exhibits different patterns, depending on a high or low matrix Young’s modulus.•The impact of OM pores development degree on DAGP can be ignored at TOC < 5%.
