The paper shows the results of computer simulation of holes punching in steel pipes of oil-gas wells using cumulative charges. The holes make possible quick re-circulation of an exploited medium and renewal of oil-field development. Because of the conditions in a well (large depth, high pressure), limited place for the charges, and requirement of punching of the holes with precisely determined diameter and depth, specially designed charges must be applied. They have to generate a punching element (puncher) that is something between shaped charge jet and explosively formed projectile (EFP). Analyses of punching abilities of such charges (especially in a complex system of wellbore pipes and layers of sand, borehole fluid, and air filling and separating them) are possible only when the methods of computer physics are applied. The results of computer simulation based on a new version of free particle method [11, 14] are given and their comparison with experimental results is presented. New version of a free particle method makes possible computer simulation of the problem with very complex initial-boundary conditions.
