| Abstract: |
| The operating process of oil well perforator relates to detonation,including the formation,the propagation and the interaction with other materials of explosive wave; interface collision,including the forming,the stretching of jet under high pressure and high temperature condition; and penetration,including the collision of jet and target,the notch-forming and dynamic response of target; and so on.In order to study the operating process and mechanism of oil well perforator,reduce design cost,and shorten design period,this paper introduced Eulerian numerical method of simulating the whole process of oil well perforator,the process consists of explosive ignition,the jet formation,the jet penetrating steel target,well liquid,and concrete target.The content introduced include mathematic model,discrete method,corresponding constitutive model,and coupled method of calculation and theoretical analysis which was used to save calculation time.At the end of paper,the numerical simulation results were compared with those of experiment,the comparison shows that the simulation results agrees well with the experiment data,and that the method is feasible and effective. |
