Abstract:
In recent years, the proportion of unconventional energy has increase in the whole energy system. Deep research about the influence factors of crack propagation has big significance in efficient energy exploration. In the paper, four groups of low permeable sandstones in different depths are applied to do the hydraulic fracturing experiments. Through CT scanning technique and 3-D reconstruction algorithm, the authors obtain the characteristics of crack propagation and spatial distribution, and discus the effect of buried depth to the crack propagation.
