A numerical simulation is conducted in perforation effect in the process of perforating charge explosion impact dynamics response process using finite element method and thought, can be used in the establishment of petroleum pipe computational model for the analysis of numerical column explosion shock dynamic response, formed a set of effective calculation method, the calculation through the numerical simulation, get different perforation phase and perforation number of working conditions under the conditions of explosion load output characteristic as well as the superposition ofenhanced forms, characteristics and regularity of output loading explosive loading are preliminary, this has provided the important theory support to enhance safety of petroleum perforation and enhance the efficiency of perforation and reasonable arrangement of perforating technology.
