During perforating，the high velocity jet penetrates the casing-cement-formation assembly. This not only causes damage to the cement sheath but also leads to bonding damage at the casing-cement interface. Such degradation tends to cause cross-flow of wellbore fluids along channels in the casing-cement interface，ultimately severely shortening the lifespan of oil and gas wells. Given this，a numerical model of high velocity jet penetration into the casing-cement-formation after perforating charge explosion is established using the fluid solid coupling method. The dynamic damage evolution law of the casing-cement bonding interface in the process of penetration is analyzed，and the effects of the cement sheath material parameter （shear modulus），cohesive unit parameter （fracture energy） and casing types on the damage area and maximum damage radius of the bonding interface are investigated. The results show that with the penetrating of jet，damage appears at the casing-cement sheath bonding interface，and the damage zone continuously expands. When the jet penetrates into the formation，the damage area reaches the maximum. With the increasing of shear modulus or fracture energy of cement sheath，the damage degree of the bonding interface decreases. Increasing borehole cleaning or using fiber containing cement slurry can reduce the damage of jet penetration to the bonding interface. When aluminum alloy，titanium alloy，nickel base alloy and other highly resistant casings are used，the damage area and maximum damage radius of the casing-cement bonding interface increase significantly during perforation penetration. The findings of this research provide theoretical support for wellbore integrity protection and engineering parameters optimization during perforating.
