Abstract The influence of complex geostress on the penetration depth of shaped charge into sandstone was analyzed and a formula for penetration depth under complex geostress was developed. The penetration depth of shaped charge into sandstone was simulated with the numerical method based on the constitutive model of sandstone and ALE algorithm. The influences of complex geostress on the shape of the hole and the energy of the sandstone during perforating were discussed. Comparisons of the results from the analytical analysis，numerical simulation and experiments were performed. The results show that the geostress has marked influence on the penetration depth. Compared to the geostress parallel to the perforating direction，the geostress perpendicular to the perforating direction has more pronounced effect on the penetration depth. Due to the greater geostress perpendicular to the perforating direction，the penetration depth becomes shallower，and the radius of the perforating aperture is larger. At the same time，the sandstone can absorb the elastic strain energy more. The proposed analytical equation and numerical method can simulate the penetration process of shaped charge into sandstone and predict the penetration depth respectively.

Key words： rock mechanics complex geostress shaped charge penetration depth
