N2 - The technologies of high charge perforator and high density perforator are widely used in domestic and international oil-gas wells perforating job, which leads to the increase of the explosion load intensity, resulting in more string damage accidents, and seriously affects the normal production of oil and gas. The software of LS-DYNA was used to measure the dynamic response of the perforating gun under four types of perforation conditions. It analyzes perforating gun head's forms and characteristics of output load under different working conditions, and also analyzes the impact on perforating gun's structural strength under different axial and radial load. These conclusions provide an important theoretical reference for reasonable arranging the perforating technology, improving perforation safety and reducing the well perforating accidents.
